After the configuration, run the display ip vpn-instance verbose command on the UPE and the
PE, and you can see the configuration of the VPN instances. By running the ping -vpn-
instance, you can see that the UPE and the PE can ping the connected CEs.
Step 4 Set up an MP-IBGP adjacency between UPE and SPE, and between PE and SPE.

NOTE
If multiple interfaces on a PE are bound to the same VPN, you must specify the source address when you
run the ping -vpn-instance command to ping the CE connected to the peer PE. That is, specify -a source-
ip-address in the ping -vpn-instance vpn-instance-name -a source-ip-address destination-address
command. Otherwise, the ping operation may fail.
