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. Processing steps 1. Use the display current-configuration configuration bgp command to verify that the peer's AS number is correct. 2. Use the display bgp ipv6 peer command to verify that the peer's IPv6 address is correct. 3. If a loopback interface is used, verify that the loopback interface is specified with the peer connect-interface command. 4. If the peer is not directly connected, verify that the peer ebgp-max-hop command is configured. 5. Verify that a valid route to the peer is available. 6. Use the ping command to verify the connectivity to the peer. 7. Use the display tcp ipv6 status command to verify the TCP connection. 8. Check whether an ACL is applied to disable TCP port 179. 252
