Operation Manual – IPv6 Routing
H3C S3610&S5510 Series Ethernet Switches
Chapter 5 IPv6 BGP Configuration
5-28
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.
5.10 Troubleshooting IPv6 BGP Configuration
5.10.1 No IPv6 BGP Peer Relationship Established
I. Symptom
Display BGP peer information using the
display bgp ipv6 peer
command. The state of
the connection to the peer cannot become established.
II. Analysis
To become IPv6 BGP peers, any two routers need to establish a TCP session using
port 179 and exchange open messages successfully.
III. Processing steps
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.
