Ama-domain amabili ebhuloho kuqoqo elilodwa le-IOS XR awasiwo i-LAN eyodwa
Ukufaka ama-domain amabili ebhuloho ngaphansi kweqoqo elilodwa lebhuloho akuhlanganisi ukudluliswa kwawo. Funda iqoqo, i-domain kanye nokuxhumeka ngakunye njengezendlalelo ezihlukene.
Ama-host amabili ku-router eyodwa ye-IOS XR awakwazi uku-pingiselana, kanti ikhophi yokuhlela ibukeka sengathi kufanele bakwazi. Womabili ama-subinterface avela ngaphansi kweqoqo elifanayo lebhuloho, amagama ahluka ngohlamvu olulodwa, futhi i-commit idlule ngaphandle kwesikhalo. Okushodayo yizinga elilodwa lohlelo lwezigaba: iqoqo lebhuloho liyisitsha, futhi i-domain ngayinye yebhuloho engaphakathi kulo iyidomain yayo yokusakaza enobulungu bayo. Engeza i-host yesithathu futhi isithombe ngokuvamile siba kubi kakhulu kunokuba sicace.
| Object | Owns | Does not own |
|---|---|---|
| Bridge group | a named container for domains | any forwarding or MAC learning |
| Bridge domain | one broadcast domain, MAC table, flooding scope | the VLAN match on an ingress port |
| Attachment | which frames from which interface and tag enter the domain | which other domains they can reach |
Qala ngesibonakaliso bese ufunda uye phezulu
Ama-host ahlulekayo ngaphakathi kwe-subnet eyodwa ngenkathi ama-interface ebika ukuthi ase-up futhi amarekhodi e-ARP engalokothi agcwale, kuwuphawu lwenkinga yobulungu be-domain, hhayi inkinga yokuhambisa. Izinkinga zokuhambisa ngokuvamile zikunika i-ICMP unreachable noma i-next hop ekhona; i-domain yokusakaza engekho ikunika ukuthula esigabeni sesibili. Hlola ukuthi izixhumanisi ezimbili zikuyo i-domain eyodwa yebhuloho yini ngaphambi kokuba ubheke ikheli le-IP elilodwa. Uma zingekho, awukho umsebenzi wamakheli ongazihlanganisa.
Iqoqo lebhuloho liyisitsha nje, akukho okunye
Kuhlelo lwezigaba lwe-VPN yesigaba 2 se-IOS XR, iqoqo lebhuloho libamba i-domain eyodwa noma ngaphezulu yebhuloho, futhi iqoqo ngokwalo alishintshi lutho. Ama-domain amabili ngaphansi kweqoqo elilodwa ayizelamani, awawona amalungu e-LAN eyodwa, nakuba ikhophi yokuhlela ifundeka sengathi afakwe ngaphakathi. Leyo hlelo iyenziwe ngamabomu: iqoqo yindawo lapho uhlela khona izinsizakalo, futhi i-domain yindawo lapho ukudluliswa kwenzeka khona ngempela.
Umhlahlandlela wezinsizakalo zamaphuzu amaningi esigaba 2 we-Cisco uchaza i-domain yebhuloho njenge-domain yokusakaza ephethe amachweba angokwenyama noma angokomqondo, eshintsha nge-MAC yendawo ekuyiwa kuyo, efunda amakheli omthombo futhi ekhipha i-unicast engaziwa, ukusakaza kanye ne-multicast ngaphakathi kwaleyo domain kuphela. Funda uhlelo lwezigaba kulo mhlahlandlela ngaphambi kokufunda ikhophi yakho yokuhlela.
I-domain yebhuloho ingumnikazi wokudluliswa nokufunda
Ukufunda kwe-MAC kugciniwe ku-domain, ngakho isiteshi esifundwe ku-domain eyodwa asibonakali ku-domain engumfowabo. Ukukhipha kulandela umngcele ofanayo, yikho ukusakaza okuthunyelwa i-host eyodwa akukaze kufinyelele i-host ekulelinye i-domain. Amaqembu e-split-horizon ngaphakathi kwe-domain, isimo samalungu kanye nanoma yikuphi ukulawulwa kokudluliswa okuhleliwe, kube sekuqhubeka kunciphisa imiphumela efanelekayo.
I-pseudowire noma i-virtual forwarding instance iyisixhumanisi sensizakalo esiya ku-domain. Akulona igama elifanayo leqoqo lebhuloho elingumzali, futhi ukulithatha kanjalo yikho okwenza umkhawulo womhlinzeki uphele nezinsizakalo ezimbili obekufanele zihlukaniswe kodwa zingahlukaniswanga.
Isixhumanisi sinquma ukuthi yimaphi amafreyimu afikayo
Ngaphansi kwe-domain kunesixhumanisi: i-interface noma i-subinterface, ukufakwa okuhambisana nakho, noma yikuphi ukusebenza kwethegi kanye ne-domain ehlanganyela nayo. I-subinterface enombolo yayo ngengozi ebukeka njenge-VLAN akuwona isivumelwano samafreyimu, futhi ichweba elilodwa langokwenyama lingondla ama-domain amabili ngokuhambisana okubili okuhlukene. Bhala i-interface yokungena, ithegi ehambisanayo, isenzo sethegi kanye ne-domain okuqondiwe kuyo, bese ubhala uhlangothi lokuphuma ngokwahlukile.
Qhathanisa leso sivumelwano phakathi kwezinsizakalo ezimbili ngaphambi kokuhambisa ikhophi yokuhlela. Lapho womabili ama-domain engaphansi kweqoqo elilodwa futhi elilodwa kuphela lawo liphethe ithrafikhi, umehluko cishe uhlala usesixhumanisini hhayi ku-domain.
Uma umklamo uphinda uhambe phakathi kwama-subnet, isixhumanisi sesigaba 3 singenye into enekheli le-gateway nomgomo wayo. Igama le-domain yebhuloho alichazi lutho mayelana nokuthi iyiphi i-gateway eyisebenzelayo.
Qinisekisa ngenguqulo esetshenzisiwe ngaphambi kokuhlela kabusha
Sebenzisa imiyalo yokusebenza yenguqulo ngokwayo ukubuka i-domain hhayi ikhophi yokuhlela esebenzayo. show l2vpn bridge-domain detail ibika ama-domain kanye nesimo sezixhumanisi zawo, futhi show l2vpn forwarding bridge-domain enezinketho ze-MAC ikhombisa ukuthi yini efundwe kuphi. Uma ikheli le-MAC livela ku-domain eyodwa hhayi komunye umfowabo, uhlelo lwezigaba lwenza ngqo lokho ebeluhlelelwe ukukwenza.
Bese ubala zonke i-domain kanye nesixhumanisi ngaphansi kweqoqo ngaphambi kokushintsha noma yini, futhi ugcine ikhophi yokuhlela ekhona ukuze iqhathaniswe. Igama lento elijwayelekile akulona ubufakazi bokuthi zonke izinsizakalo ezifakwe ngaphakathi zabelana ngobubanzi bayo.
