Hlola i-router MAC ye-EVPN ngaphambi kokusola i-underlay

Amakheli amabili e-MAC avela kupakethe elilodwa le-VXLAN, futhi lilodwa kuphela lawo elingelomgcini wendawo ekuyiwa kuyo. Ku-EVPN VXLAN IP-VRF kuya ku-IP-VRF umklamo, i-MAC yendawo ekuyiwa kuyo yangaphakathi iyi-router MAC emenyezelwe yi-router yokuphuma, kuyilapho i-MAC yendawo ekuyiwa kuyo yangaphandle ingeyalokho okuletha ipakethe kusixhumanisi se-underlay esilandelayo. Ukudida lezi ezimbili kuthumela abantu ku-underlay bayofuna iphutha elingekho lapho. Yenza ukuhlolwa ngokulandelana.

Isinyathelo ngasinye siphendula umbuzo owodwa, futhi impendulo yokuqala inquma ukuthi izinyathelo ezilandelayo zihlobene yini.

1. Funda umzila we-prefix kanye nemiphakathi yawo

Qala emzileni hhayi ekubanjweni kwamapakethe:

show bgp l2vpn evpn route type prefix 10.20.0.0/24

Umzila we-Type 5 umenyezela i-prefix ye-IP. Kumodeli ye-IP-VRF engenaso isixhumanisi futhi uthwala i-L3 VNI kanye nomphakathi onwetshiwe we-router MAC, futhi umphakathi lowo yiwo okhomba indawo yokugcina yokuhlela yokuphuma. Funda umphakathi esikhundleni sokucabanga ukuthi i-MAC ifakiwe ku-NLRI ye-prefix, ngoba akunjalo. Uma umzila ukhona futhi umphakathi unamathisiwe, izinga lokulawula selivele lenze ingxenye yalo.

2. Qinisekisa ukuthi imuphi umodeli wokudlulisela osetshenziswayo

Imodeli engenaso isixhumanisi kanye nokuphindaphinda ngenkomba ye-overlay kuyizinhlelo ezimbili ezihlukene ezisekelwayo. Imodeli engenaso isixhumanisi ihlela ipakethe, yakha uhlaka lwangaphakathi lwendawo yokugcina yokuhlela ekude, bese ilufaka ku-VTEP yokuphuma.

Ekuphindaphindeni ngenkomba ye-overlay, i-router engenayo idinga ukusesha okwengeziwe ukuze ixazulule ukugxuma okulandelayo ngaphambi kokudlulisela. Womabili amamodeli avumelekile, futhi inqubo esebenzayo incike ekutheni iyiphi i-fabric yakho eyisebenzisayo. Ukusebenzisa umqondo wokugxuma okulandelayo oqondile ku-fabric eyakhiwe ngenye indlela kuveza isiphetho esibonakala silungile ekubanjweni futhi singalungile ekubuyekezweni komklamo.

3. Lindela izindima ezimbili ezihlukene ze-MAC

I-MAC yendawo ekuyiwa kuyo yangaphakathi iyi-router MAC emenyezelwe ye-router yokuphuma. I-MAC yendawo ekuyiwa kuyo yangaphandle ukugxuma okulandelayo kokulethwa kwasekhaya, okungaba i-router ye-underlay futhi kungashintsha kukho konke ukugxuma. Ukuzibona zihlukile kujwayelekile, futhi ukuzibona zilingana kuyisigameko hhayi imfuneko. Ukubanjwa okubonisa ikheli elifana ne-chassis ngaphakathi kanye nekheli lomzimba lokugxuma okulandelayo ngaphandle kuchaza ngqo ukufakwa okuhloswe.

4. Thatha inani elivela ku-chassis njengokukhetha kokusetshenziswa

Ipulatifomu ingase ithole i-router MAC yayo emenyezelwe kusukela kubunjalo besistimu noma be-chassis, futhi leso yisinqumo sokusetshenziswa hhayi umthetho wephrothokholi. Hlola imodeli yokwabiwa nokweqile yomthengisi ngaphambi kokufunda noma yini efomini lekheli.

Izinhlelo ezimbili zokusetshenziswa ezozombili ziyavumelana zingamenyezela ama-router MAC abukeka ehlukile, yingakho ukuwaqhathanisa phakathi kwabathengisi kufakazela okuncane kakhulu.

5. Ungashintshi lutho kuze kube isimo asivumelani

Ukuze kubuyekezwe, qhathanisa umzila we-prefix okhethiwe, imiphakathi yawo enwetshiwe, ukugxuma okulandelayo kwe-BGP, i-L3 VNI kanye nesimo sokudlulisela esivela kukho. Bese ulebula izihloko zangaphakathi nezingaphandle ekubanjweni.

Uma lezo ezinhlanu zivumelana, i-MAC ebukeka iyinqaba yenza umsebenzi wayo, futhi ukuyishintsha kuzophula indawo yokugcina yokuhlela esikhundleni sokulungisa iphutha lekheli. Uma zingavumelani, manje usuyazi ukuthi iyiphi inkambu engalungile, futhi ushintsho luqondisiwe hhayi ukuqagela. Incazelo ye-prefix ye-IP ye-EVPN ingumthombo okufanele ucatshangelwe kuleyo ngxoxo, ngoba ichaza kokubili imodeli kanye nomphakathi othwala inani.
