To become IPv6 BGP peers, any two routers need to establish a TCP session using port 179 and 

exchange open messages successfully. 

1) Use 

the 

display current-configuration command to verify the peer’s AS number. 

2) Use 

the 

display bgp ipv6 peer command to verify the peer’s IPv6 address. 

3)  If the loopback interface is used, check whether the peer connect-interface command is 

configured. 

4)  If the peer is not directly connected, check whether the peer ebgp-max-hop command is 

configured. 

5)  Check whether a route to the peer is available in the routing table. 

6) Use 

the 

ping command to check connectivity. 

7) Use 

the 

display tcp ipv6 status command to check the TCP connection. 

8)  Check whether an ACL for disabling TCP port 179 is configured.
