[LB-bgp-af-ipv6] peer 102::2 as-number 200
# Configure Router C.
<RouterC> system-view
[RouterC] ipv6
[RouterC] bgp 200
[RouterC-bgp] router-id 4.4.4.4
[RouterC-bgp] ipv6-family
[RouterC-bgp-af-ipv6] peer 102::1 as-number 200
3. Configure LB as a route reflector, and configure Router B and Router C as its clients.
[LB-bgp-af-ipv6] peer 101::2 reflect-client
[LB-bgp-af-ipv6] peer 102::2 reflect-client
4. Verify the configuration:
Execute the display bgp ipv6 routing-table command on Router B and Router C. Both have learned
the network 1::/64.
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.
Solution
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. If the peer ttl-security hops command is configured, verify that the command is configured on the
peer, and the hop-count values configured on them are greater than the number of hops between
them.
6. Verify that a valid route to the peer is available.
7. Use the ping command to verify the connectivity to the peer.
8. Use the display tcp ipv6 status command to verify the TCP connection.
9. Verify whether an ACL is applied to disable TCP port 179.
