I-tunnel yomqondo ye-Junos yizixhumi ezimbili, hhayi isixhumi esisodwa

Ngaphakathi kwerutha, i-interface ye-lt- ibukeka njengekhebula impela, futhi umbono lowo uwona odala iningi lokudideka. Akusona isixhumi esisodwa kodwa izixhumi ezimbili: uhlangothi ngalunye lungolwesinye isevisi, uhlangothi ngalunye lunokugoqwa kwalo, futhi ipheya lidlulisa kuphela lapho zombili izinsizakalo zixhunywe kahle. Yenza izinyathelo ezinhlanu ezingezansi ngokulandelana, futhi thatha ukuzibophezela okuhlanzekile njengokuqala kokuqinisekisa, hhayi ukuphela komsebenzi. Isinyathelo ngasinye sishiya irekhodi onjiniyela olandelayo angalihlola ngaphandle kokuphinda uphenyo.

Isinyathelo 1: bhala iphepha lokusebenza lezixhumi

Ngaphambi kokuthinta ukucushwa, dweba ukuthi yini okufanele ixhume nani. Uhlangothi olulodwa luqeda isekethe ye-Layer 2 yephoyinti-kuya-kwephoyinti, olunye lujoyina isimo se-VPLS, futhi i-tunnel yomqondo ihlezi phakathi kwazo ithwala amafreyimu isuka kwelinye iya kwelinye. Qamba zombili izinsizakalo ngokusobala, ngoba isekethe yephoyinti-kuya-kwephoyinti, isimo se-VPLS kanye nokuxhumana kwe-EVPN-VXLAN akukwazi ukushintshana ngoba nje ngakunye kungachazwa njengokuthunga.

Rekhoda izinombolo zamayunithi kuzo zombili iziphelo nokuthi iyiphi isevisi okungokwayo ngayinye. Lelo phepha liyincwadi yodwa ezohlala ilungile ngemva kwezinguquko ezintathu nokubuyiselwa emuva.

Isinyathelo 2: qinisa amayunithi angomlingani kanye nokugoqwa

Amayunithi amabili kufanele abe kuyo i-interface efanayo ye-tunnel yomqondo futhi akhombe komunye nomunye, futhi iyunithi ingaba nomlingani oyedwa kuphela. Imibhalo ye-Juniper mayelana ne-tunnel yomqondo isho zombili lezi zivimbelo kanye nokugoqwa okusekelwayo kanye nezinsiza zendlela ezisetshenziswa i-interface. Qinisekisa lezi ngokumelene nehardware efakiwe kanye nokukhishwa, hhayi ngokumelene nesibonelo saselabhorethri esivela kwelinye ikhadi lomugqa. Iyunithi engumlingani ekhonjiswe kuma-interface amabili ehlukene e-lt iyazibophezela ngokuhlanzekile futhi ayidlulisi lutho.

Bese ukhetha ukugoqwa okuhambisana nesevisi ohlangothini ngalunye. Umdwebo wepheya ubukeka kanje:

set interfaces lt-0/0/0 unit 0 encapsulation vlan-ccc
set interfaces lt-0/0/0 unit 0 peer-unit 1
set interfaces lt-0/0/0 unit 1 encapsulation vlan-vpls
set interfaces lt-0/0/0 unit 1 peer-unit 0

Ukukopisha amagama angukhiye e-Ethernet-CCC ne-Ethernet-VPLS ku-sevisi ye-VLAN ngaphandle kokuvumelanisa ukumakwa kungenye indlela evamile yokukhiqiza ipheya ephakamayo kodwa engadlulisi lutho.

Isinyathelo 3: xhumanisa uhlangothi ngalunye nesevisi yalo

Iyunithi ngayinye ingeyencazelo yesevisi, futhi isevisi kufanele ngempela iyifake. Ezinhlelweni ze-MX Layer 2 ezisekelwayo, imibhalo ikhomba ubulungu be-bridge-domain noma be-VPLS njengento eyenza ukudluliswa kube nhlangothi zombili, okusho ukuthi ipheya elingumlingani elifanele elineyunithi engenabo ubulungu liyipheya lamaphoyinti okugcina akhuluma nalutho. Engeza ubulungu ekuzibophezeleni okufanayo namayunithi, ukuze kokubili kungavelani nhlobo.

Setha ukusayinwa kwe-pseudowire kanye nobulungu besimo njengengxenye yoshintsho olufanayo, ngoba isiphelo esikude sesekethe yiso esinikeza uhlangothi lwe-VPLS into yokufunda.

Isinyathelo 4: bika izinsiza kanye nosayizi wefreyimu

Isixhumi sangaphakathi sisasebenzisa izinsiza zokudlulisa. Imibhalo ibala imithelela yomkhawulo wobubanzi wendlela yezintambo zomqondo, ngakho hlola leyo esikhundleni sokucabanga ukuthi okwangaphakathi kusho mahhala.

Qondanisa i-MTU yesevisi kanye nemodeli yokumaka kuzo zombili izixhumi kanye ne-pseudowire ekude. Ungakopishi inani le-MTU lesibonelo ngaphandle kokuthola ukuthi yimaphi amakhanda asetshenziswayo isilungiselelo esifanele, ngoba ukugxuma kwangaphakathi okunciphisa isabelomali buthule kuzohluleka khona lapho ithrafikhi yabasebenzisi inkulu khona.

Isinyathelo 5: qinisekisa ukudluliswa, bese ufuna amaluphu

Thumela ithrafikhi kuzo zombili izinhlangothi futhi uhlole isimo sesevisi, hhayi isimo se-interface kuphela. I-show interfaces lt-0/0/0 ikutshela ukuthi ipheya liphezulu ngokomthetho, futhi i-show vpls connections ikutshela ukuthi isimo sinokuxhumana okungafundwa kukho yini. Akukho kukho kokubili okufakazela ukuthi ifreyimu engena kwesinye isevisi yaphuma kwesinye, ngakho kuhlola lokho ngokusobala. Thumela kusuka kusibungu ohlangothini olulodwa kuya kusibungu kolunye uhlangothi, kuyilapho isimo sesevisi sibonakala ngesikhathi ithrafikhi ihamba.

Ekugcineni, hlola ukuthi ingabe enye indlela yomzimba noma yomqondo isivele ijoyina isizinda esifanayo se-Ethernet. Ukwengeza lesi sixhumi kungashintsha ukuziphatha kokugcwala futhi kudale iluphu eyayingekho ngaphambili, futhi uphawu luzovela kwenye indawo ngokuphelele. Hlela ukweqilela okufunayo esikhundleni sokuthola indlela ye-Layer 2 engagadiwe ngesikhathi sezehlo.
