Cisco heeft dit document vertaald via een combinatie van machine- en menselijke technologie om onze gebruikers wereldwijd ondersteuningscontent te bieden in hun eigen taal. Houd er rekening mee dat zelfs de beste machinevertaling niet net zo nauwkeurig is als die van een professionele vertaler.

Dit document beschrijft de verschillende BFD-flap-redenen (Bidirectional Forwarding Detection) op een Cisco vEdge-router.
Cisco raadt u aan kennis te hebben van Cisco SDWAN-oplossing.
Dit document is gebaseerd op Cisco Cloud vEdge-router die 19.2.1 draait.
De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk levend is, zorg er dan voor dat u de mogelijke impact van om het even welke opdracht begrijpt.
Dit document is niet beperkt tot enige specifieke topologie.
IP-adressen en kleuren van bepaalde belangrijke onderdelen in dit document:
Samengesteld | System-IP | VPN 0 IP/kleur | VPN 0 IP/kleur |
VEDGE-1 | 10.13.13.13 | 192.168.1.4 / mpls | 192.168.2.4 / mpls |
VEDGE-2 | 10.15.15.15 | 192.168.1.8 / biz-internet | 192.168.2.8 / biz-internet |
vSmart | 10.8.8.8 | 192.168.1.3 / standaard | NA |
vManager | 10.7.7.7 | 192.168.1.1 / standaard | NA |
De mogelijke waarden van 'flap-ratio' op een Cisco vEdge-router zijn:
1. B-deleted - BFD daalt omdat het bedieningspaneel het heeft verwijderd.
U heft twee meldingen op wanneer BFD is verwijderd. Eén voor BFD omlaag en één wanneer BFD wordt verwijderd.
2. Time-out - geen BFD-respons van het afstandsgedeelte.
3. Remote-end - Remote-kant heeft een BFD-pakket verzonden dat aangeeft dat het naar een lagere toestand is gegaan.4.
4. na - niet van toepassing. Dit wordt ingesteld wanneer de BFD-sessie voor het eerst wordt gemaakt en wanneer de BFD-sessie wordt gestart.
Voer een port-hop-over-VEDGE-1 router uit en reproduceren dit scenario:
