# Configure Switch C as a route reflector, Switch B and Switch D as its clients.
[SwitchC-bgp-af-ipv6] peer 101::2 reflect-client
[SwitchC-bgp-af-ipv6] peer 102::2 reflect-client
Use the display bgp ipv6 routing-table command on Switch B and Switch D
respectively, you can find both of them have learned the network 1::/64.
Symptom
Display BGP peer information 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 need to establish a TCP session using
port 179 and exchange open messages successfully.
