iESI efanayo ngaphakathi kwesiza, ihlukile phakathi kweziza: ukuthungwa kwe-Junos
I-interconnect ESI eyodwa ibopha amasango asebenzela isiza; isiza sesibili sidinga eyaso. Isitatimende se-peer esithwala lobo buqobo sithuthe phakathi kokukhishwa.
Amapheya amabili amasango asebenzela izikhungo ezimbili zedatha, futhi othile kufanele anqume ukuthi zingaki izindinganiso ze-interconnect ESI ezidingwa umklamo. Impendulo ingeyodwa ngeqembu lamasango, hhayi eyodwa nge-fabric ngayinye futhi hhayi eyodwa ngesango ngalinye. Ukwenza lokhu ngokungalungile kukhiqiza i-fabric ebonakala ukuthi ilungisiwe futhi ekhetha i-forwarder engalungile, noma ihlanganisa iziza ezimbili okwakufanele zihlale zihlukene. Umthetho kanye nokuhlukile kwawo kufanele kubhalwe eduze kohlu lwamasango.
Imikhakha emibili, imithetho emibili
Ngaphakathi kwesiza, amasango e-interconnect ayisipele asebenza njengendawo yokugcina eyodwa ye-multihomed, ngakho abelana nge-interconnect ESI eyodwa. Ama-peer awo kufanele abone ilungu elilodwa elinengqondo esikhundleni samabili azimele. Yilokho okushiwo yindima yonke yeningi elabiwe.
Phakathi kweziza, iqembu ngalinye lamasango lithola inani lalo. Izikhungo ezimbili zedatha ezabelana ngesihlonzi esisodwa ziba iqembu elilodwa le-multihomed endaweni yokulawula, okuvamise ukungabi yilokho okuhlosiwe umklamo wokuthungwa ezweni lonke le-WAN. Iziza ezimbili eqenjini elilodwa zizuza njengefa izimo zokwehluleka zomunye nomunye.
Ngaphakathi kwesiza: ubuqobo obubodwa beqembu
Nika ipheya inani elifanayo kuwo womabili ama-peer, endaweni yesevisi efanayo, futhi ulibhale ku-inventri yezihlonzi zenethiwekhi esikhundleni somucu wengxoxo. Ukungafani phakathi kwamalungu amabili yisimo sokwehluleka esikhiqiza iqembu elinelungu elilodwa futhi ngaphandle kwesixwayiso esicacile. Qhathanisa womabili amalungu ngaphambi kokukholwa isikhathi sokusebenza esisebenzayo.
Imodeli esekelwayo i-all-active. Isethenjwa esifanayo asikufaki ukusebenza kwe-single-active, izihlonzi ze-LACP ezitholakala ngokuzenzakalela kanye nezinketho ze-source-bmac zalobu buqobo bokuthungwa, ngakho umklamo owacabanga okukodwa kulokho udinga ukubuyekezwa ngaphambi kokuthi isihlonzi sikhethwe. Leso sithiyo siwufakazo lomklamo, hhayi umbhalo waphansi.
Phakathi kweziza: amanani ahlukene, noma ukuhlanganiswa ngamabomu
Inani elihlukile lesiza ngasinye ligcina amaqembu amabili amasango ehlukene. Uma inhloso iwukwandisa ngempela iqembu elilodwa le-multihomed phakathi kweziza, lokho kuwukwakheka okunye okunemiphumela yayo yokubambezeleka, ukwehluleka nokudluliswa, futhi kufanele kunqunywe njengokwakheka hhayi njengokukhetha isihlonzi. Cela leso sinqumo ngokubhaliwe ngaphambi kwewindi lokunakekela.
Bhala umehluko ohlosiwe kuphulani, ukuze unjiniyela wakamuva okhopha ithempulethi yesiza esisebenzayo angalethi nesihlonzi sayo kanye nayo.
Isitatimende se-peer siyingxenye yobuqobo
Isango ngalinye eqenjini libala ama-peer alo endawo ngokukhethekile ngekheli le-loopback, futhi lobo budlelwano buhlala ezingeni le-EVPN lomhlaba wonke hhayi ngaphakathi kwe-MAC-VRF eyodwa. Ukulibeka endaweni engalungile yezigaba kuyindlela evamile yokukhiqiza ukulungiselelwa okuthola i-commit kodwa okungakhi iqembu nanini. Funda isigaba sethenjwa kanye, bese ulandela sona.
Igama lesitatimende nalo lishintshile. I-Juniper yaqamba kabusha isitatimende se-interconnect peer-gateways ngo-24.2R1 futhi yabuyisela isimo esiqondene ne-interconnect sokuxhumanisa kwezikhungo zedatha ngo-24.4R1. Ngakho isiqeshana esithathwe kokukhishwa kwesikhashana singasebenzisa igama elingamukelwa inguqulo esetshenzisiwe, noma okuphambene nalokho. Bhala ukukhishwa okwavela kukho isiqeshana eduze nesiqeshana uqobo.
Okungakwenzi ukwabelana nge-iESI
Akukuchazeli ama-route target, ama-VNI noma i-instance ye-EVPN yendawo. Lokho kuhlala kuyilungiselelo elihlukile okufanele livumelane ezinhlangothini zombili, futhi isihlonzi esivumelanayo kuyilapho i-route target ingavumelani sikhiqiza iqembu elakheka futhi elingathwali lutho. Qhathanisa izinhlangothi zombili zalokho kulungiselelwa ngendlela eyodwa.
Futhi akufakazeli ukufinyeleleka kwama-peer noma ukukhethwa kwe-designated forwarder. Hlola i-unicast kanye nokuziphatha okudingekayo kwe-broadcast ne-multicast esimweni esijwayelekile, bese uphinda ngokususa isango elilodwa ukuze ilungu elisele lithwale iqembu lodwa.
Yilokho kuqalisa kwesibili okuqinisekisa ukuthi iqembu lingokoqobo.
Gcina ubulungu obubonakele kanye nomongo wesevisi kanye nemiphumela yokuhlola. Ukushintsha kwesihlonzi kamuva kungabuyekezwa khona njengoshintsho lwe-multihoming, okuyikho ngempela, hhayi njengokuhlela kobuhle komucu. Imiphumela iwubufakazi obukuphela kokuthi isihlonzi senza lokho okushiwo umdwebo.
