The output shows that Switch A and Switch C communicate through Switch B, and Switch C has
two routes to reach network 1200::0/64: Switch C<—>Switch B<—>Switch A, which is the
currently active route; Switch C<—>Switch D<—>Switch A, which is the backup route.
When the link Switch C<—>Switch B<—>Switch A fails, Switch C can quickly detect the failure on
Switch B.

Troubleshooting IPv6 BGP configuration

IPv6 BGP peer relationship not established

Symptom
Display BGP peer information by using the display bgp ipv6 peer command. The state of the connection
to the peer cannot become established.
Analysis
To become IPv6 BGP peers, any two routers must establish a TCP session using port 179 and exchange
open messages successfully.
