After completing the configurations, issue the display ip vpn-instance command on the PEs to view
the configuration of the VPN instance. Use the ping command to test connectivity between the PEs
and their attached CEs. The PEs can ping their attached CEs. The following takes PE 1 as an
example:
[PE1] display ip vpn-instance
Total VPN-Instances configured : 1
VPN-Instance Name RD Create Time
vpn1 100:1 2006/08/13 09:32:45
[PE1] ping -vpn-instance vpn1 10.1.1.1
