Yam yuavtsum tau kawm uantej rau RIP
Koj yuav tsum configure ip routing hais kom ua ua ntej koj configure RIP.
Kev txwv rau RIP
Routing Information Protocol (RIP) siv hop suav ua tus ntsuas ntsuas tus nqi ntawm cov kev sib txawv. Lub hop suav yog tus naj npawb ntawm cov khoom siv uas tuaj yeem hla hauv txoj kev. Ib lub network txuas ncaj qha muaj qhov ntsuas ntawm xoom; ib qho kev sib txuas tsis tau muaj qhov ntsuas ntawm 16. Qhov kev ntsuas kev txwv no ua rau RIP tsis haum rau cov tes hauj lwm loj.
Nco tseg
Yog tias RIP configuration tsis muaj cov lus qhia hauv lub network uas npog ib qho interface tshwj xeeb, peb xav kom koj tsis txhob teeb tsa RIP hauv qab qhov interface ntawd. Yog tias RIP tau teeb tsa ntawm qhov kev sib txuas no, kev faib tawm ntawm txoj hauv kev los ntawm lwm txoj kev sib txuas mus rau RIP, tau txais los ntawm qhov interface, tsis ua haujlwm.
Cov ntaub ntawv hais txog Configuring RIP
RIP Tshajview
Routing Information Protocol (RIP) siv tshaj tawm UDP cov ntaub ntawv pob ntawv los pauv cov ntaub ntawv routing. Cisco software xa cov ntaub ntawv hloov tshiab txhua 30 vib nas this, uas yog hu ua kev tshaj tawm. Yog tias ib lub cuab yeej tsis tau txais kev hloov tshiab los ntawm lwm lub cuab yeej rau 180 vib nas this lossis ntau dua, cov cuab yeej tau txais cim cov kev pabcuam los ntawm cov cuab yeej tsis hloov kho yog siv tsis tau. Yog tias tseem tsis tau hloov kho tom qab 240 vib nas this, lub cuab yeej tshem tawm tag nrho cov lus nkag mus rau cov khoom siv tsis hloov tshiab.
Ib lub cuab yeej uas tab tom khiav RIP tuaj yeem tau txais lub neej ntawd network los ntawm kev hloov tshiab los ntawm lwm lub cuab yeej uas tab tom khiav RIP, lossis lub cuab yeej tuaj yeem tsim lub network siv RIP. Nyob rau hauv ob qho tib si, lub neej ntawd network tau tshaj tawm los ntawm RIP rau lwm tus neeg nyob ze RIP.
Cisco kev siv ntawm RIP Version 2 (RIPv2) txhawb nqa cov ntawv nyeem thiab cov lus digest algorithm 5 (MD5) authentication, txoj kev summarization, classless interdomain routing (CIDR), thiab variable-ntev subnet qhov ncauj qhov ntswg (VLSMs).
RIP Routing Hloov tshiab
Routing Information Protocol (RIP) xa cov xov xwm hloov tshiab ntawm lub sijhawm tsis tu ncua thiab thaum lub network topology hloov. Thaum ib lub cuab yeej tau txais RIP routing hloov tshiab uas suav nrog kev hloov pauv mus rau qhov nkag, lub cuab yeej hloov kho nws cov lus routing kom muaj kev cuam tshuam txoj kev tshiab. Tus nqi metric rau txoj kev yog nce los ntawm 1, thiab tus neeg xa khoom tau qhia tias yog lub hop tom ntej. RIP cov cuab yeej tuav tsuas yog txoj kev zoo tshaj plaws (txoj kev nrog tus nqi qis tshaj plaws) mus rau qhov chaw. Tom qab hloov kho nws lub rooj sib tham, lub cuab yeej tam sim ntawd pib xa RIP routing hloov tshiab kom ceeb toom rau lwm lub network ntawm kev hloov pauv. Cov kev hloov tshiab no raug xa tawm ntawm nws tus kheej ntawm cov kev hloov kho tsis tu ncua uas RIP cov khoom xa tuaj.
RIP Routing Metric
Routing Information Protocol (RIP) siv ib qho kev ntsuas kev ntsuas los ntsuas qhov kev ncua deb ntawm qhov chaw thiab qhov chaw nres nkoj. Txhua lub plhaw hauv txoj hauv kev los ntawm qhov chaw mus rau qhov chaw mus rau qhov chaw yog muab tus nqi hop-count, uas feem ntau yog 1. Thaum ib lub cuab yeej tau txais kev hloov pauv hloov tshiab uas muaj qhov hloov tshiab lossis hloov chaw nkag mus rau lub network, lub cuab yeej ntxiv 1 rau tus nqi metric qhia. nyob rau hauv qhov hloov tshiab thiab nkag mus rau hauv lub network nyob rau hauv lub routing rooj. Tus IP chaw nyob ntawm tus neeg xa khoom siv los ua lub hop tom ntej. Yog hais tias lub network interface tsis tau teev nyob rau hauv lub rooj sib tham, nws yuav tsis raug tshaj tawm nyob rau hauv ib qho kev hloov tshiab RIP.
Authentication hauv RIP
Cisco kev siv ntawm Routing Information Protocol (RIP) Version 2 (RIPv2) txhawb kev lees paub, kev tswj xyuas qhov tseem ceeb, kev sib sau ua ke, tsis muaj kev sib txuas lus sib txuas (CIDR), thiab qhov sib txawv-ntev qhov ncauj qhov ntswg (VLSMs).
Los ntawm lub neej ntawd, software tau txais RIP Version 1 (RIPv1) thiab RIPv2 pob ntawv, tab sis xa tsuas yog RIPv1 pob ntawv. Koj tuaj yeem teeb tsa lub software kom tau txais thiab xa tsuas yog RIPv1 pob ntawv. Xwb, koj tuaj yeem teeb tsa lub software kom tau txais thiab xa tsuas yog RIPv2 pob ntawv. Txhawm rau hla tus cwj pwm tsis zoo, koj tuaj yeem teeb tsa RIP version uas qhov cuam tshuam xa. Ib yam li ntawd, koj tuaj yeem tswj tau li cas cov pob ntawv tau txais los ntawm kev sib txuas ua tiav.
RIPv1 tsis txhawb kev lees paub. Yog tias koj xa thiab tau txais RIP v2 pob ntawv, koj tuaj yeem pab RIP authentication ntawm ib qho interface. Cov saw tseem ceeb txiav txim siab cov txheej txheem ntawm cov yuam sij uas tuaj yeem siv rau ntawm lub interface. Kev lees paub, suav nrog kev lees paub qhov tseeb, yog ua rau ntawm qhov sib txuas nkaus xwb yog tias cov saw tseem ceeb raug teeb tsa.
Yog xav paub ntxiv txog cov chains tseem ceeb thiab lawv cov teeb tsa, saib "Kev Tswj Xyuas Cov Ntsiab Lus" hauv "Configuring IP Routing Protocol-Independent Features" tshooj hauv Cisco IOS IP Routing: Protocol-Independent Configuration Guide.
Cisco txhawb nqa ob hom kev lees paub ntawm qhov kev sib txuas uas RIP tau qhib: kev lees paub qhov tseeb thiab cov lus digest algorithm 5 (MD5) authentication. Plain-text authentication yog qhov kev lees paub qhov tseeb hauv txhua pob ntawv RIPv2.
Nco tseg
Tsis txhob siv cov ntawv pov thawj dawb hauv RIP pob ntawv rau kev ruaj ntseg, vim hais tias tus yuam sij tsis muaj kev lees paub raug xa mus rau hauv txhua pob ntawv RIPv2. Siv cov ntawv pov thawj dawb-ntawv pov thawj thaum kev ruaj ntseg tsis yog qhov teeb meem; rau example, koj tuaj yeem siv cov ntaub ntawv pov thawj tseeb los xyuas kom meej tias cov tswv tsis raug cai tsis koom nrog kev ua haujlwm.
Sib pauv cov ntaub ntawv Routing
Routing Information Protocol (RIP) feem ntau yog ib qho kev tshaj tawm xov xwm, thiab rau RIP routing hloov tshiab kom ncav cuag nonbroadcast tes hauj lwm, koj yuav tsum teeb tsa Cisco software kom tso cai rau qhov kev sib pauv ntawm cov ntaub ntawv routing. Txhawm rau tswj cov txheej txheem ntawm kev sib txuas uas koj xav hloov pauv hloov pauv hloov tshiab, koj tuaj yeem kaw qhov kev xa tawm cov hloov tshiab ntawm cov kev cuam tshuam tshwj xeeb los ntawm kev teeb tsa passive-interface router configuration command. Koj tuaj yeem siv daim ntawv teev npe offset kom nce cov kev ntsuas nkag thiab tawm mus rau cov kev kawm ntawm RIP. Optionally, koj tuaj yeem txwv cov npe offset nrog rau cov npe nkag lossis ib qho interface. Routing protocols siv ob peb lub sijhawm uas txiav txim siab hloov pauv xws li zaus ntawm kev hloov pauv hloov tshiab, lub sijhawm ntev ua ntej txoj hauv kev yuav tsis raug, thiab lwm yam tsis muaj. Koj tuaj yeem kho cov timers no los kho cov txheej txheem kev ua haujlwm kom zoo dua rau koj cov kev xav tau hauv internet. Koj tuaj yeem hloov kho timer hauv qab no:
- Tus nqi (lub sij hawm, nyob rau hauv vib nas this, nruab nrab ntawm kev hloov tshiab) ntawm uas routing hloov tshiab raug xa
- Lub caij nyoog ntawm lub sij hawm, nyob rau hauv vib nas this, tom qab uas ib txoj kev tau tshaj tawm tsis raug
- Lub caij nyoog, nyob rau hauv vib nas this, thaum lub sij hawm routing cov ntaub ntawv hais txog kev zoo dua yog suppressed
- Tus nqi ntawm lub sij hawm, nyob rau hauv vib nas this, uas yuav tsum dhau ua ntej ib txoj kev raug tshem tawm ntawm lub routing rooj
- Lub sijhawm rau qhov kev hloov kho tshiab yuav raug ncua
Koj tuaj yeem kho tus IP routing kev txhawb nqa hauv Cisco software kom ua kom nrawm dua ntawm ntau yam IP routing algorithms, thiab li no, ua rau rov qab sai dua rau cov khoom siv rov qab. Tag nrho cov txiaj ntsig yog kom txo qis kev cuam tshuam rau cov neeg siv kawg ntawm lub network hauv cov xwm txheej uas qhov kev rov qab sai yog qhov tseem ceeb
Tsis tas li ntawd, tsev neeg chaw nyob tuaj yeem muaj timers uas siv tau rau tsev neeg qhov chaw nyob (lossis Virtual Routing thiab Forwarding [VRF]) piv txwv). Lub timers-basic hais kom ua yuav tsum tau teev tseg rau tsev neeg chaw nyob lossis lub kaw lus ua haujlwm rau lub sijhawm timers-basic hais kom raug siv txawm hais tias lub timer uas tau teeb tsa rau RIP routing. Lub VRF tsis tau txais cov txiaj ntsig timer los ntawm lub hauv paus RIP teeb tsa. VRF yuav ib txwm siv lub kaw lus lub sijhawm ncua sij hawm tshwj tsis yog tias lub sijhawm hloov pauv meej meej siv cov lus txib timers-basic.
RIP Txoj Kev Summarization
Kev nthuav qhia txoj hauv kev hauv RIP Version 2 txhim kho scalability thiab efficiency hauv cov tes hauj lwm loj. Summary IP chaw nyob txhais tau hais tias tsis muaj kev nkag mus rau cov menyuam yaus txoj kev (txoj kev uas tau tsim rau ib qho kev sib txuas ntawm tus kheej IP chaw nyob uas muaj nyob rau hauv qhov chaw nyob luv luv) hauv RIP routing rooj, txo qhov loj ntawm lub rooj thiab tso cai rau lub router ua haujlwm ntau dua. txoj kev.
Summary IP chaw nyob ua haujlwm tau zoo dua li ntau qhov kev tshaj tawm tus kheej IP rau cov laj thawj hauv qab no:
- Cov kev qhia luv luv hauv RIP database tau ua tiav ua ntej.
- Ib qho kev cuam tshuam me nyuam txoj hauv kev uas suav nrog hauv txoj hauv kev uas tau sau tseg raug hla raws li RIP saib los ntawm cov ntaub ntawv routing, txo cov sijhawm ua haujlwm. Cisco routers tuaj yeem sau cov kev hauv ob txoj hauv kev:
- Tsis siv neeg, los ntawm kev sau cov npe subprefix rau hauv chav kawm ntawv ciam teb thaum hla cov chav kawm sib txuas (tsis siv neeg cov ntsiab lus).
Nco tseg: Tsis siv neeg cov ntsiab lus tau qhib los ntawm lub neej ntawd.
Raws li kev teeb tsa tshwj xeeb, tshaj tawm cov ntsiab lus hauv zos IP chaw nyob ntawm qhov kev sib tham tshwj xeeb (ntawm lub network nkag mus rau server) kom cov chaw nyob tuaj yeem muab rau cov neeg siv xov tooj.
Thaum RIP txiav txim siab tias qhov chaw nyob yuav tsum muaj nyob rau hauv RIP database, cov ntsiab lus nkag yog tsim nyob rau hauv RIP routing database. Tsuav muaj me nyuam txoj hauv kev rau qhov chaw nyob, qhov chaw nyob tseem nyob hauv cov ntaub ntawv routing. Thaum tus menyuam kawg txoj kev raug tshem tawm, cov ntsiab lus nkag kuj raug tshem tawm ntawm cov ntaub ntawv. Cov txheej txheem ntawm kev tuav cov ntaub ntawv nkag no txo cov naj npawb ntawm nkag hauv cov ntaub ntawv vim tias txhua tus menyuam txoj hauv kev tsis tau teev nyob rau hauv ib qho kev nkag, thiab kev nkag nkag nws tus kheej raug tshem tawm thaum tsis muaj cov menyuam txoj kev siv tau lawm rau nws.
RIP Version 2 txoj kev sib sau ua ke yuav tsum tau tshaj tawm qhov qis tshaj plaws ntawm "txoj kev zoo tshaj" ntawm kev nkag nkag, lossis qhov ntsuas qis tshaj ntawm txhua txoj kev me nyuam tam sim no, yuav tsum tau tshaj tawm. Qhov kev ntsuas zoo tshaj plaws rau kev sib sau ua ke yog xam ntawm txoj kev pib lossis thaum muaj kev hloov kho metric ntawm cov kev tshwj xeeb ntawm lub sijhawm tshaj tawm, thiab tsis yog lub sijhawm cov kev sib sau ua ke tau tshaj tawm.
Lub ip summary-address rip routerconfiguration command ua rau lub router sau cov txheej txheem ntawm kev kawm ntawm RIP Version 2 lossis rov faib rau RIP Version 2. Cov kev tswj hwm yog tshwj xeeb tshaj yog muaj feem xyuam rau cov ntsiab lus.
Saib "Route Summarization Example, nyob rau nplooj 22" ntu kawg ntawm tshooj no rau examples ntawm kev siv cais qab ntug. Koj tuaj yeem txheeb xyuas cov kev twg uas tau sau tseg rau kev sib tham siv qhov qhia ip raws tu qauv EXEC hais kom ua. Koj tuaj yeem tshawb xyuas cov ntsiab lus chaw nyob nkag hauv RIP database. Cov kev nkag no yuav tshwm sim hauv cov ntaub ntawv tsuas yog hais txog cov kev qhia me nyuam uas cuam tshuam. Txhawm rau tso saib cov ntsiab lus chaw nyob nkag hauv RIP routing database nkag yog tias muaj cov kev cuam tshuam raug suav nrog raws li qhov chaw nyob, siv cov qhia ip rip database hais kom ua hauv EXEC hom. Thaum tus me nyuam txoj hauv kev kawg rau qhov chaw nyob hauv cov ntsiab lus tsis raug, qhov chaw nyob cov ntsiab lus tseem raug tshem tawm ntawm lub rooj sib tham.
Split Horizon Mechanism
Nquag, cov khoom siv uas txuas nrog rau kev tshaj tawm-hom IP tes hauj lwm thiab uas siv qhov kev ncua deb-vector routing raws tu qauv siv cov txheej txheem sib cais qab ntug kom txo tau qhov muaj peev xwm ntawm routing loops. Txoj kev sib cais qab ntug txheej txheem thaiv cov ntaub ntawv hais txog txoj hauv kev los ntawm kev tshaj tawm los ntawm lub cuab yeej tawm ntawm ib qho kev sib cuam tshuam los ntawm cov ntaub ntawv ntawd keeb kwm. Qhov kev coj cwj pwm no feem ntau optimizes kev sib txuas lus ntawm ntau yam khoom siv, tshwj xeeb tshaj yog thaum sib txuas. Txawm li cas los xij, nrog cov xov xwm tsis tshaj tawm, xws li Frame Relay thiab Switched Multimegabit Digital System (SMDS), cov xwm txheej tuaj yeem tshwm sim uas tus cwj pwm no tsawg dua qhov zoo tagnrho. Hauv cov xwm txheej zoo li no, koj tuaj yeem xav lov tes taw lub qab ntug nrog Routing Information Protocol (RIP).
Yog tias qhov kev sib txuas tau teeb tsa nrog qhov chaw nyob IP thib ob thiab qhib lub qab ntug, cov kev hloov tshiab yuav tsis raug muab los ntawm qhov chaw nyob thib ob. Yog tias txoj kab nruab nrab qhib tau qhib, ib qho kev hloov kho tshiab tau muab los ntawm ib tus xov tooj network. Split horizon tsis yog neeg xiam oob qhab los ntawm lub neej ntawd rau kev sib cuam tshuam siv ib qho ntawm X.25 encapsulations. Rau tag nrho lwm cov encapsulations, cais qab ntug yog enabled los ntawm lub neej ntawd.
Interpacket ncua sijhawm rau RIP hloov tshiab
Los ntawm lub neej ntawd, software ntxiv tsis muaj ncua sij hawm ntawm pob ntawv hauv ntau pob ntawv RIP hloov tshiab raug xa mus. Yog hais tias koj muaj ib tug high-end router xa mus rau ib tug tsawg-ceev router, tej zaum koj yuav xav ntxiv xws li interpacket ncua rau RIP hloov tshiab, nyob rau hauv ntau ntawm 8 mus rau 50 milliseconds.
RIP Optimization ntawm WAN Circuits
Cov cuab yeej siv tau siv rau hauv kev sib txuas-taw qhia kev tes hauj lwm kom tso cai rau kev sib txuas mus rau ntau qhov chaw nyob deb. Circuits ntawm WAN yog tsim los ntawm kev thov thiab raug tso tseg thaum cov tsheb khiav qis. Nyob ntawm daim ntawv thov, kev sib txuas ntawm ob qhov chaw rau cov neeg siv cov ntaub ntawv yuav luv luv thiab tsis tshua muaj.
Qhov chaw IP chaw nyob ntawm RIP Routing Hloov tshiab
Los ntawm lub neej ntawd, Cisco software validates qhov chaw nyob IP ntawm cov ntaub ntawv Routing Protocol (RIP) routing tshiab. Yog hais tias qhov chaw nyob tsis siv tau, lub software pov tseg qhov hloov tshiab routing. Koj yuav tsum lov tes taw qhov kev ua haujlwm no yog tias koj xav tau txais kev hloov tshiab los ntawm lub cuab yeej uas tsis yog ib feem ntawm lub network no. Txawm li cas los xij, disabling no functionality tsis pom zoo nyob rau hauv ib txwm muaj xwm txheej.
Neighbor Router Authentication
Koj tuaj yeem tiv thaiv koj lub router los ntawm kev tau txais cov kev dag ntxias hloov tshiab los ntawm kev teeb tsa cov neeg nyob sib ze router authentication. Thaum configured, cov neeg zej zog authentication tshwm sim thaum twg routing hloov tshiab yog sib pauv ntawm cov neeg zej zog routers. Qhov kev lees paub no ua kom ntseeg tau tias lub router tau txais cov ntaub ntawv qhia kev txhim khu kev qha los ntawm qhov chaw ntseeg siab.
Yog tias tsis muaj kev txheeb xyuas tus neeg nyob ze, tsis muaj kev tso cai lossis txhob txwm ua phem rau kev hloov kho tshiab tuaj yeem cuam tshuam kev nyab xeeb ntawm koj lub network tsheb. Kev cuam tshuam txog kev ruaj ntseg tuaj yeem tshwm sim yog tias ib tog neeg tsis sib haum xeeb cuam tshuam lossis txheeb xyuas koj lub network tsheb. Rau example, ib lub router uas tsis tau tso cai tuaj yeem xa cov ntaub ntawv tsis tseeb hloov tshiab los txhawb koj lub router kom xa tsheb mus rau qhov chaw tsis raug. Qhov kev hloov pauv no tuaj yeem raug txheeb xyuas kom paub cov ntaub ntawv tsis pub lwm tus paub txog koj lub koom haum lossis tsuas yog siv los cuam tshuam koj lub koom haum lub peev xwm los sib txuas lus zoo siv lub network. Cov neeg nyob sib ze authentication tiv thaiv ib qho kev dag txog txoj kev hloov tshiab tsis tau txais los ntawm koj lub router.
Thaum cov neeg nyob sib ze authentication tau teeb tsa ntawm lub router, lub router authenticates lub hauv paus ntawm txhua qhov kev hloov pauv hloov tshiab pob ntawv uas nws tau txais. Qhov no ua tiav los ntawm kev sib pauv ntawm tus yuam sij authenticating (qee zaum hu ua lo lus zais) uas paub txog kev xa thiab txais router.
Muaj ob hom kev txheeb xyuas cov neeg nyob sib ze uas siv: cov ntawv nyeem yooj yim authentication thiab Message Digest Algorithm Version 5 (MD5) authentication. Ob daim ntawv ua haujlwm zoo ib yam, tshwj tsis yog tias MD5 xa ib qho "lus digest" es tsis yog tus yuam sij authenticating nws tus kheej. Cov lus digest yog tsim siv tus yuam sij thiab cov lus, tab sis tus yuam sij nws tus kheej tsis raug xa mus, tiv thaiv nws los ntawm kev nyeem thaum nws raug xa mus. Plain text authentication xa tus yuam sij authenticating nws tus kheej hla cov hlau.
Nco tseg
Nco ntsoov tias daim ntawv pov thawj dawb tsis pom zoo siv los ua ib feem ntawm koj lub tswv yim kev ruaj ntseg. Nws qhov kev siv tseem ceeb yog kom tsis txhob muaj kev hloov pauv hloov mus rau cov txheej txheem routing. Txawm li cas los xij, siv MD5 authentication, yog ib qho kev pom zoo siv kev nyab xeeb. Hauv kev lees paub cov ntawv nyeem yooj yooj yim, txhua tus neeg nyob sib ze uas koom nrog router yuav tsum qhia tus yuam sij rau kev lees paub. Tus yuam sij no tau teev tseg ntawm txhua lub router thaum lub sijhawm teeb tsa. Ntau tus yuam sij tuaj yeem teev nrog qee qhov kev cai; txhua tus yuam sij yuav tsum raug txheeb xyuas los ntawm tus lej tseem ceeb. Feem ntau, thaum kev hloov pauv hloov pauv raug xa mus, qhov kev lees paub hauv qab no tshwm sim:
- Ib lub router xa ib qho kev hloov tshiab nrog tus yuam sij thiab tus lej tseem ceeb rau tus neeg nyob ze router. Hauv cov txheej txheem uas tuaj yeem muaj ib tus yuam sij nkaus xwb, tus lej tseem ceeb yog ib txwm xoom. Tus txais (cov neeg nyob sib ze) router xyuas tus yuam sij tau txais tawm tsam tib tus yuam sij khaws cia hauv nws lub cim xeeb.
- Yog tias ob tus yuam sij sib tw, tus txais router txais cov pob ntawv hloov tshiab. Yog tias ob tus yuam sij tsis sib xws, pob ntawv hloov tshiab yuav raug tsis lees paub.
MD5 authentication ua hauj lwm zoo ib yam li cov ntawv dawb authentication, tshwj tsis yog tias tus yuam sij yuav tsis raug xa mus hla cov hlau. Hloov chaw, lub router siv MD5 algorithm los tsim "cov lus digest" ntawm tus yuam sij (tseem hu ua "hash"). Cov lus digest yog ces xa mus es tsis txhob ntawm tus yuam sij nws tus kheej. Qhov no ua kom ntseeg tau tias tsis muaj leej twg tuaj yeem mloog ntawm kab thiab kawm cov yuam sij thaum sib kis.
Lwm daim ntawv ntawm kev txheeb xyuas tus neeg nyob ze router yog los teeb tsa kev tswj hwm qhov tseem ceeb siv cov saw tseem ceeb. Thaum koj teeb tsa cov saw tseem ceeb, koj teev cov yawm sij nrog lub neej, thiab Cisco IOS software tig los ntawm txhua tus yuam sij no. Qhov no txo qis qhov yuav ua rau cov yuam sij yuav raug cuam tshuam. Txhawm rau nrhiav kom tiav cov ntaub ntawv teeb tsa rau cov saw tseem ceeb, xa mus rau "Kev Tswj Xyuas Cov Ntsiab Cai" ntu hauv Configuring IP Routing Protocol-Independent Features module ntawm Cisco IOS IP Routing: Protocol-Independent Configuration Guide.
IP-RIP ncua sij hawm pib duaview
IP-RIP Ncua Sijhawm Pib feature yog siv rau Cisco cov khoom siv los ncua kev pib ntawm Routing Information Protocol Version 2 (RIPv2) cov neeg nyob sib ze sib tham kom txog rau thaum lub network sib txuas ntawm cov neeg nyob sib ze ua haujlwm tau zoo, yog li xyuas kom meej tias tus lej ntawm cov lus thawj zaug digest. algorithm 5 (MD5) pob ntawv uas lub cuab yeej xa mus rau cov khoom tsis yog Cisco cov neeg nyob sib ze yog 0. Tus cwj pwm tsis zoo rau lub cuab yeej teeb tsa los tsim RIPv2 cov neeg nyob sib ze sib tham nrog cov neeg nyob ze siv MD5 authentication yog pib xa MD5 pob ntawv thaum lub cev sib cuam tshuam. nce.
IP-RIP Ncua Sijhawm Pib feature feem ntau yog siv thaum Cisco cov cuab yeej teeb tsa los tsim RIPv2 cov neeg zej zog kev sib raug zoo siv MD5 authentication nrog cov khoom siv tsis yog Cisco hla lub Ncej Relay network. Thaum RIPv2 cov neeg nyob sib ze txuas nrog dhau Frame Relay, nws muaj peev xwm rau qhov sib txuas sib txuas nrog Frame Relay network kom nce thaum lub hauv paus Frame Relay circuits tseem tsis tau npaj xa thiab tau txais cov ntaub ntawv.
Thaum lub serial interface yog nce thiab lub Frame Relay circuits tseem tsis tau ua hauj lwm, tej MD5 pob ntawv uas lub cuab yeej sim kis tau tus serial interface yog poob. Thaum MD5 pob ntawv raug poob vim hais tias cov ncej Relay Circuit Court uas cov pob ntawv yuav tsum tau xa tawm tseem tsis tau ua haujlwm, tus naj npawb ntawm cov thawj MD5 pob ntawv tau txais los ntawm cov neeg nyob ze cov cuab yeej tom qab Frame Relay circuits ua haujlwm yuav ntau dua 0. Cov khoom siv uas tsis yog Cisco yuav tsis tso cai rau MD5-authenticated RIPv2 cov neeg nyob ze sib tham pib thaum tus naj npawb ntawm thawj MD5 pob ntawv tau txais los ntawm lwm lub cuab yeej ntau dua 0.
Qhov sib txawv ntawm cov neeg muag khoom siv ntawm MD5 authentication rau RIPv2 tej zaum yog vim qhov tsis meej pem ntawm RFC (RFC 2082) ntsig txog cov pob ntawv poob. RFC 2082 qhia tias cov khoom siv yuav tsum tau npaj los lees txais ib tus lej ntawm 0 lossis tus lej ib ntu siab dua tus lej kawg tau txais. Yog xav paub ntxiv txog MD5 cov lus txais tos rau RIPv2, saib ntu 3.2.2 ntawm RFC 2082 ntawm cov hauv qab no url: http://www.ietf.org/rfc/rfc2082.txt.
IP-RIP Ncua Sijhawm Pib feature tau txais kev txhawb nqa hla lwm hom kev sib txuas xws li Fast Ethernet thiab Gigabit Ethernet.
Cisco pab kiag li lawm tso cai rau MD5-authenticated RIPv2 cov neeg nyob ze sib tham pib thaum tus naj npawb ntawm thawj MD5 pob ntawv tau txais los ntawm lwm yam khoom siv ntau dua 0. Yog tias koj siv Cisco nkaus xwb hauv koj lub network, koj tsis tas yuav siv tus IP. -RIP Delay Start feature.
Offset-list
Daim ntawv teev npe offset yog ib txoj hauv kev los nce cov kev ntsuas nkag thiab tawm mus rau cov kev kawm ntawm RIP. Qhov no yog ua los muab ib lub zos mechanism rau nce tus nqi ntawm routing metrics. Optionally, koj tuaj yeem txwv cov npe offset nrog rau cov npe nkag lossis ib qho interface.
Timers
Routing raws tu qauv siv ntau lub sijhawm uas txiav txim siab qhov hloov pauv raws li qhov zaus ntawm kev hloov pauv hloov tshiab, lub sijhawm ntev ua ntej txoj kev ua tsis raug, thiab lwm yam tsis muaj. Koj tuaj yeem kho cov timers no los kho cov txheej txheem kev ua haujlwm kom zoo dua rau koj cov kev xav tau hauv internet. Koj tuaj yeem hloov kho timer hauv qab no:
- Tus nqi (lub sij hawm nyob rau hauv vib nas this ntawm kev hloov tshiab) ntawm uas routing hloov tshiab raug xa
- Lub caij nyoog ntawm lub sijhawm (hauv vib nas this) tom qab uas txoj kev tau tshaj tawm tsis raug
- Lub ncua sij hawm (hauv vib nas this) thaum lub sij hawm uas routing cov ntaub ntawv hais txog txoj kev zoo dua yog suppressed
- Tus nqi ntawm lub sijhawm (hauv vib nas this) uas yuav tsum dhau ua ntej ib txoj hauv kev raug tshem tawm ntawm lub rooj routing
- Lub sijhawm rau qhov kev hloov kho tshiab yuav raug ncua
Nws kuj tseem tuaj yeem hloov kho tus IP routing kev txhawb nqa hauv software kom muaj kev sib koom ua ke sai dua ntawm ntau yam IP routing algorithms, thiab, yog li ntawd, rov qab sai dua rau cov routers tsis tau. Tag nrho cov txiaj ntsig yog kom txo qis kev cuam tshuam rau cov neeg siv kawg ntawm lub network hauv cov xwm txheej uas qhov kev rov qab sai yog qhov tseem ceeb.
