Huawei AR1200 Series Enterprise Routers
Configuration Guide - VPN
After the configuration, run the display bgp peer or display bgp vpnv4 all peer command on
each PE device. You can see the BGP peer relationship is set up between the PEs, and the status
is Established.
Step 6 Verify the configuration.
After the configuration, the Spoke-CEs can ping through each other. Run the tracert command,
and you can see that the traffic between Spoke-CEs is forwarded through Hub-CE. You can also
deduce the number of forwarding devices between Spoke-CEs based on the TTL in the Ping
result.
Consider Spoke-CE 1 as an example:
[Spoke-CE1] ping 120.1.1.1
PING 120.1.1.1: 56
--- 120.1.1.1 ping statistics ---
[Spoke-CE1] tracert 120.1.1.1
traceroute to
1 100.1.1.2 8 ms
2 110.2.1.2
3 110.2.1.1
4 110.1.1.2
5 120.1.1.2
6 120.1.1.1
Run the display bgp routing-table command on Spoke-CE, and you can see that there are
repetitive AS numbers in AS paths of the BGP routes toward the remote Spoke-CE.
Consider Spoke-CE 1 as an example:
[Spoke-CE1] display bgp routing-table
Total Number of Routes: 6
BGP Local router ID is 100.1.1.1
