IPv6 Multicast Overview
Iqembu le-IPv6 multicast iqembu elingenangqondo labamukeli elifuna ukuthola ukusakazwa kwedatha okuthile. Leli qembu alinayo imingcele ebonakalayo noma yendawo; abamukeli bangatholakala noma kuphi ku-inthanethi noma kunoma iyiphi inethiwekhi yangasese. Abamukeli abanentshisekelo yokwamukela idatha egeleza eqenjini elithile kufanele bajoyine iqembu ngokusayina idivayisi yabo yasendaweni. Lokhu kusayina kufinyelelwa ngephrothokholi ye-MLD.
Amadivayisi asebenzisa iphrothokholi ye-MLD ukuze afunde ukuthi amalungu eqembu akhona yini kuma-subnet awo anamathiselwe ngokuqondile. Ababungazi bajoyina amaqembu okusakaza okuningi ngokuthumela imilayezo yombiko we-MLD. Inethiwekhi ibe isiletha idatha enambeni okungenzeka ayinamkhawulo yabamukeli, isebenzisa ikhophi eyodwa kuphela yedatha yokusakaza okuningi ku-subnet ngayinye. Abasingathi be-IPv6 abafisa ukuthola ithrafikhi baziwa njengamalungu eqembu.
Amaphakethe alethwa kumalungu eqembu akhonjwa ngekheli leqembu elilodwa lokusakaza okuningi. Amaphakethe we-Multicast alethwa eqenjini kusetshenziswa ukwethembeka kwemizamo engcono kakhulu, njengamaphakethe we-IPv6 unicast.
Imvelo yokusakaza okuningi iqukethe abathumeli nabamukeli. Noma yimuphi umsingathi, kungakhathaliseki ukuthi uyilungu leqembu, angathumela eqenjini. Nokho, amalungu eqembu kuphela athola umlayezo.
Ikheli lokusakaza okuningi likhethwa abamukeli eqenjini lokusakaza okuningi.Abathumeli basebenzisa leli kheli njengekheli le-datagram ukufinyelela wonke amalungu eqembu.
Ubulungu eqenjini lokusakaza okuningi buyashintshashintsha; ababungazi bangajoyina futhi bahambe noma nini. Awukho umkhawulo endaweni noma inombolo yamalungu eqenjini lokusakaza okuningi. Umsingathi angaba yilungu lamaqembu amaningi okusakaza angaphezu kwelilodwa ngesikhathi. Iqembu le-multicast lisebenza kangakanani, ubude balo, nobulungu balo kungahluka eqenjini neqembu futhi ngezikhathi ezithile. Iqembu elinamalungu lingase lingabi nawo umsebenzi

I-IPv6 Multicast Ukuqaliswa Komzila
Isofthiwe ye-Cisco isekela imigomo elandelayo ukuze kusetshenziswe umzila we-IPv6 wokusakaza okuningi:

• I-MLD isetshenziswa amadivayisi e-IPv6 ukuthola abalaleli be-multicast kuzixhumanisi ezinamathiselwe ngqo. Kunezinguqulo ezimbili ze-MLD:
  • Inguqulo 1 ye-MLD isekelwe kunguqulo 2 ye-Internet Group Management Protocol (IGMP) ye-IPv4.
  • Inguqulo 2 ye-MLD isuselwe enguqulweni yesi-3 ye-IGMP ye-IPv4.
• I-IPv6 multicast yesofthiwe ye-Cisco isebenzisa kokubili inguqulo ye-MLD 2 kanye nenguqulo ye-MLD 1. Inguqulo ye-MLD 2 ibuyela emuva ngokugcwele nenguqulo 1 ye-MLD (echazwe ku-RFC 2710). Ababungazi abasekela kuphela inguqulo 1 ye-MLD basebenzisane nocingo olusebenzisa inguqulo ye-MLD 2. Ama-LAN axubile anako kokubili abasingathi benguqulo ye-MLD 1 kanye nenguqulo 2 ye-MLD ayasekelwa ngokufanayo.
• I-PIM-SM isetshenziswa phakathi kwamadivayisi ukuze bakwazi ukulandelela ukuthi yimaphi amaphakethe okusakaza okuningi okufanele adluliselwe kwelinye kanye nama-LAN awo axhumeke ngokuqondile.
• I-PIM ku-Source Specific Multicast (PIM-SSM) ifana ne-PIM-SM enekhono elengeziwe lokubika intshisekelo yokwamukela amaphakethe asuka ekhelini elithile lomthombo (noma kuwo wonke amakheli omthombo athile) ukuya ekhelini le-IP lokusakaza okuningiliziwe.

Isibalo esingezansi sibonisa lapho i-MLD ne-PIM-SM zisebenza khona ngaphakathi kwendawo yokusakaza eminingi ye-IPv6.

Umfanekiso 1: IPv6 Multicast Routing Protocols Esekelwe IPv6

I-Multicast Listener Discovery Protocol ye-IPv6

Ukuqala ukusebenzisa i-multicasting ku-campus kunethiwekhi, abasebenzisi kumele baqale bachaze ukuthi ubani owamukela ukusakaza okuningi. Iphrothokholi ye-MLD isetshenziswa amadivayisi e-IPv6 ukuthola ubukhona babalaleli bokusakaza okuningi (ngokwesiboneloample, ama-node afuna ukuthola amaphakethe okusakaza okuningi) kuzixhumanisi zawo ezinamathiselwe ngokuqondile, kanye nokuthola ngokukhethekile ukuthi yimaphi amakheli okusakaza okuningi athakaselwayo kulawo ma-node angomakhelwane. Isetshenziselwa ukuthola ubulungu beqembu lendawo kanye nomthombo othize. Iphrothokholi ye-MLD ihlinzeka ngendlela yokulawula ngokuzenzakalelayo futhi ukhawulele ukugeleza kwethrafikhi yokusakaza okuningi kuyo yonke inethiwekhi yakho ngokusebenzisa imibuzo ekhethekile nabasingathi. Umehluko phakathi kwababuzi be-multicast kanye nabasingathi umi kanje:

• Umceli idivayisi yenethiwekhi ethumela imilayezo yombuzo ukuthola ukuthi imaphi amadivayisi enethiwekhi angamalungu eqembu elinikeziwe lokusakaza okuningi.
• Umsingathi umamukeli othumela imilayezo yombiko ukuze azise lowo obuza imibuzo ngobulungu bosokhaya.

Iqoqo lababuzayo nabasingathi abathola ukusakazwa kwedatha ye-multicast emthonjeni ofanayo libizwa ngokuthi iqembu lokusakaza okuningi.
Ababuzayo nabasingathi basebenzisa imibiko ye-MLD ukuze bajoyine futhi bashiye amaqembu okusakaza okuningi futhi baqale ukuthola ithrafikhi yeqembu.

I-MLD isebenzisa i-Internet Control Message Protocol (ICMP) ukuze iphathe imilayezo yayo. Yonke imilayezo ye-MLD ingeyendawo enomkhawulo we-hop ongu-1, futhi yonke inesethi yenketho yokuxwayisa. Inketho yesixwayiso isho ukuqaliswa kwesihloko senketho ye-hop-by-hop.
I-MLD inezinhlobo ezintathu zemilayezo:

• Umbuzo—Okuvamile, okuqondene neqembu, kanye namakheli okusakaza okuningi. Emlayezweni wombuzo, inkambu yekheli lokusakaza okuningi isethwe ku-0 uma i-MLD ithumela umbuzo ojwayelekile. Umbuzo ojwayelekile ufunda ukuthi imaphi amakheli okusakaza okuningi anabalaleli kusixhumanisi esinamathiselwe
  
  Imibuzo eqondene neqembu kanye ne-multicast-address-specific iyafana. Ikheli leqembu ikheli lokusakaza okuningi.
• Bika—Embikweni wombiko, inkambu yamakheli okusakaza okuningi ingeyekheli elithile le-IPv6 lokusakaza okuningi lapho umthumeli alalela khona.
• Kwenziwe—Emlayezweni owenziwe, inkambu yamakheli okusakaza okuningi ingeyekheli elithile le-IPv6 lokusakaza okuningi lapho umthombo womlayezo we-MLD ungasalaleli.

Umbiko we-MLD kufanele uthunyelwe ngekheli elivumelekile le-IPv6 lomthombo wesixhumanisi, noma ikheli elingashiwongo (::), uma isixhumi esibonakalayo sokuthumela singakatholi ikheli lendawo elivumelekile. Ukuthumela imibiko ngekheli elingashiwongo kuvunyelwe ukusekela ukusetshenziswa kwe-IPv6 multicast ku-Neghbor Discovery Protocol.

Ngokulungiselelwa okuzenzakalelayo okungenasimo, i-node iyadingeka ukuze ujoyine amaqembu amaningi okusakaza e-IPv6 ukuze kwenziwe ukutholwa kwekheli eliyimpinda (DAD). Ngaphambi kuka-DAD, okuwukuphela kwekheli indawo yokubika enalo yesixhumi esibonakalayo sokuthumela isikhashana, elingeke likwazi ukusetshenziselwa ukuxhumana. Ngakho-ke, ikheli elingashiwongo kufanele lisetshenziswe.

I-MLD ithi umphumela ovela kunguqulo 2 yenguqulo ye-MLD noma imibiko yobulungu yenguqulo ye-MLD inganqunyelwa emhlabeni wonke noma ngesixhumi esibonakalayo. Isici semikhawulo yeqembu le-MLD sinikeza ukuvikeleka ekuhlaselweni kwe-denial of service (DoS) okubangelwa amaphakethe e-MLD. Imibiko yobulungu engaphezu kwemikhawulo emisiwe ayifakiwe kunqolobane ye-MLD, futhi ithrafikhi yaleyo mibiko yobulungu eyeqile ngeke idluliselwe.

I-MLD inikeza ukwesekwa kokuhlunga umthombo. Ukuhlunga umthombo kuvumela indawo ukuthi ibike intshisekelo yokulalela amaphakethe kuphela ekhelini elithile lomthombo (elidingekayo ku-SSM), noma kuwo wonke amakheli ngaphandle kwamakheli omthombo othize athunyelwa ekhelini elithile lokusakaza okuningi.

Uma umsingathi osebenzisa inguqulo 1 ye-MLD ethumela umlayezo wokushiya, idivayisi idinga ukuthumela umlayezo wombuzo ukuze iqinisekise kabusha ukuthi lo msingathi ubengumsingathi wokugcina wenguqulo 1 ye-MLD ejoyine iqembu ngaphambi kokuthi imise ukudlulisela ithrafikhi. Lo msebenzi uthatha cishe imizuzwana emi-2. Le "leave latency" ikhona futhi kunguqulo 2 ye-IGMP ye-IPv4 multicast.

Iqembu le-MLD Access
Amaqembu okufinyelela e-MLD ahlinzeka ngokulawula ukufinyelela kowamukelayo kumadivayisi e-Cisco IPv6 multicast. Lesi sici sikhawulela uhlu lwamaqembu umamukeli angawajoyina, futhi sivumela noma sinqabe imithombo esetshenziselwa ukujoyina iziteshi ze-SSM.

• Sebenzisa i- bonisa amaqembu e-ipv6 mld [isixhumanisi-sendawo] [igama leqembu | ikheli leqembu] [interface-type interface-number] [imininingwane | sobala] umyalo wokubonisa amaqembu okusakaza okuningi axhumeke ngokuqondile kudivayisi futhi afundwe nge-MLD:

Irutha# bonisa iqembu le-ipv6 mld

Ikheli Leqembu Lobulungu Beqembu Le-MLD	Isixhumi esibonakalayo	Isikhathi Sokuphumula Siphelelwa yisikhathi
FF08::1	Gi0/4/4	00:10:22 00:04:19

• Sebenzisa i- bonisa ipv6 mfib [vrf vrf-igama] [konke | i-linkscope | verbose | iqembu-ikheli-igama | ipv6-prefix/prefix-length | Igama lomthombo-ikheli | esibonakalayo | isimo | isifinyezo] umyalo bonisa okufakiwe okudlulisela phambili nezixhumi ezibonakalayo ku-IPv6 Multicast Forwarding Information Base (MFIB).

I-ex elandelayoampi-le ikhombisa okufakiwe kokudlulisela kanye nezindawo ku-MFIB ezicaciswe nekheli leqembu elithi FF08:1::1:

Umzila# bonisa ipv6 mfib ff08::1

• Sebenzisa i- bonisa i-ipv6 mld interface [inombolo yohlobo] umyalo wokubonisa ulwazi oluhlobene nokusakaza okuningi mayelana ne-

Okulandelayo ngu-sample okukhiphayo kusuka ku umbukiso ipv6 mld esibonakalayo umyalo we-Gigabit Ethernet interface 0/4/4:

Umzila# bonisa ipv6 mld isixhumi esibonakalayo se-gigabitethernet 0/4/4

• Sebenzisa i- bonisa ipv6 mld [vrf vrf-igama] traffic umyalo wokubonisa izibali zethrafikhi ze-MLD:

Umzila# bonisa ithrafikhi ye-ipv6 mld

• Sebenzisa i- bonisa ipv6 mroute [vrf vrf-igama] [isixhumanisi-sendawo | [igama leqembu | iqembu-ikheli [umthombo-ikheli | umthombo-igama] ] ] umyalo wokubonisa ulwazi kuthebula le-PIM topology:

Umzila# bonisa ipv6 mroute ff08::1
