Lipotso tse atisang ho botsoa (FAQ)
- Q: OSPF ke eng, 'me e fapana joang le RIP?
A: OSPF (Open Shortest Path First) ke sehokelo-state routing protocol e bokellang tlhahisoleseding e mabapi le likhokahano tsa marang-rang ho haha 'mapa oa topology. E fapane le RIP (Routing Information Protocol) ka ho sebelisa algorithm e tsoetseng pele le ho fana ka li-advan tse fapaneng.tage fetile RIP. - Q: Joang ho beha e ikhethang router ID bakeng sa mong le e mong fapoha ka OSPF phetolo?
A: Ka OSPF phetolo, o ka beha e ikhethang router ID bakeng sa mong le e mong fapoha ka ho latela mehato e thathamisitsoeng bukeng mosebedisi. Ho bohlokoa ho etsa bonnete ba hore switjha e 'ngoe le e' ngoe e na le ID e ikhethileng ea router ho thibela litaba ka ts'ebetso ea OSPF.
Letoto la GWN78XX - Tataiso ea OSPF
FEELAVIEW
OSPF emela Open Shortest Path Pele, ke routing protocol 'me o sebelisa sehokelo-state routing algorithm, ka mantsoe a mang, e bokella tlhahisoleseding e mabapi le boemo ba mong le e mong sehokelo netweke ho haha 'mapa kakaretso ea topology netweke kaofela. OSPF ke ka hare heke protocol (IGP) tšoanang le RIP (Routing Information Protocol), ke protocol e thehiloeng dikgatotharabololong vector sebaka. OSPF e na le li-advan tse ngatatage fetang liprothokholo tse ling tsa ho tsamaisa, joalo ka RIP.
Ba bang ba AdvantagSetšoantšo sa protocol ea OSPF
- OSPF ka phetha tsela kakaretso, e leng ho fokotsa boholo ba tafole routing le ntlafatsa scalability.
- OSPF e tšehetsa IPv4 le IPv6.
- OSPF ka arola marangrang ka libaka, e leng lihlopha tse utloahalang tsa li-routers tse arolelanang boitsebiso bo tšoanang ba naha. Sena se fokotsa palo ea tlhahisoleseding ea litsela e lokelang ho fapanyetsanoa le ho sebetsoa ke router ka 'ngoe.
- OSPF ka sebelisa netefatso ho boloka phapanyetsano ya routing tlhahisoleseding pakeng tsa routers.
- OSPF e ka sebetsana le limaske tsa subnet tse bolelele bo fapaneng (VLSM), e lumellang tšebeliso e ntle ea liaterese tsa IP le moralo oa marang-rang.
Ho sena mohlalaample, re tla be re sebelisa li-switches tse peli tsa GWN781x(P) tse hokahaneng ka kotloloho (baahelani) le router e sebetsang e le seva sa DHCP. Ka kopo sheba setšoantšo se ka tlase:
TIISETSO
Mohato oa 1:
- Lumella OSPF
- Seta ID ea router
- Seta ID ea sebaka le mofuta oa sebaka
Web GUI
Ho qala ho sebelisa OSPF, ka kopo tsamaea ho Web UI → Ho tsamaisa → OSPF:
- Toggle ON OSPF le kenya Router ID (e ka ba leha e le efe IPv4 aterese) ebe Scroll down to the bottom of the page and click the "OK" konopo, ka kopo sheba palo e ka tlase:
- Ho eketsa sebaka se secha ho switjha ho ka etsoa feela ka CLI, ka kopo sheba taelo e tšoanang karolong e latelang. Hang ha sebaka se secha se eketsoa, mosebelisi a ka fetola mofuta ka ho tobetsa letšoao la edita.
- Pheta mehato e tšoanang ho li-switches tse ling.
CLI
- Kenya mokhoa oa tlhophiso oa lefats'e ka ho kenya taelo e ka tlase.
- Ebe thusa OSPF ka fapoha ka ho sebelisa taelo e ka tlase
- Beha router ID bakeng sa fapoha, ID ena e sebelisoa feela ho hlwaya fapoha le OSPF phetolo. ID e nka sebopeho sa sebopeho sa IPv4. Ho seta ID ea router, ka kopo kenya taelo e ka tlase.
- Ka ho sa feleng, switjha e behiloe ka ID ea sebaka sa 0, e leng sebaka sa mokokotlo. Sebaka sena se ke ke sa hlophisoa e le sebaka se Tloaelehileng, sebaka sa Stub, sebaka se Stubby Kahohle, kapa sebaka sa Not So Stubby. Ho sena mohlalaample, re seta switjha sebakeng sa stub 1 se se nang mofuta oa sebaka sa kakaretso, se tsejoang hape e le sebaka se Stubby Kahohle.
- Pheta mehato e tšoanang ho li-switches tse ling ha u ntse u nahana ka ho fana ka e 'ngoe le e' ngoe ea router ID e ikhethang, ho seng joalo OSPF e ka 'na ea se ke ea sebetsa joalokaha e rerile kapa e se ke ea sebetsa ho hang.
Hlokomela
Haeba kamano e haufi e thehiloe, ts'ebetso ea OSPF e hloka ho tsosolosoa hore ID ea router e sebetse. Tlhokomeliso: ketso ena e tla etsa hore OSPF e se ke ea sebetsa 'me e etse hore ho be le recalculation. Ka kopo e sebelise ka hloko.
Mohato oa 2:
- Etsa hore OSPF ka segokanyimmediamentsi sa sebolokigolo
- View boitsebiso ba boahelani
- View tafole ea ho tsamaisa le litsela tse ncha tse fumanoeng ke OSPF
Web GUI
Ho tab ea Litlhophiso tsa Interface, tobetsa letšoao la "Edita" ho nolofalletsa VLAN IP Interface.
Toggle ON OSPF ka segokanyimmediamentsi sa sebolokigolo a khetha ka nako eo Scroll down le tobetsa ka "OK" konopo.
Ka kopo etsa mehato e ts'oanang ho sesebelisoa sa bobeli, ebe ho tab ea Moahelani oa Info, tobetsa konopo ea "refresh" bakeng sa li-switches tse haufi (tse amanang ka ho toba) hore li hlahe.
E ea ho Tafole ea Routing Web UI → Routing → Tafole ea Routing ho netefatsa hore tafole ea ho tsamaisa e na le litsela tse eang ho VLAN IP Interfaces e neng e entsoe pele ka lehlakoreng le leng. Ka kopo sheba setšoantšo se ka tlase:
Ho hlahloba LSDB (Link State DataBase), tlanya tabeng ea Database Info tab, khetha mofuta (database) ebe o tobetsa konopo ea "Query" ho bona lintlha tsa Database e leng lethathamo la LSA (Link State Advertisements) tseo bohle OSPF routers sebelisa ho fumana tlhahisoleseding e mabapi le routers tse ling tse mathang OSPF protocol le ke seo thusa ho populate tafole routing bakeng sa tsela e molemohali ea ho e mong le e eang teng.
