After the configuration, run the display ip vpn-instance verbose command on the PEs, and you
can see the configuration of the VPN instances. Each PE can ping the connected CEs by using
the ping -vpn-instancevpn-name ip-address command.
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.
Step 4 Set up EBGP peer relation between the PE and the CE and import VPN routes.
NOTE
To receive the routes advertised by the Hub-CE, configure the Hub-PE to allow the ASN to be repeated
once.
