Pinging a Layer 3 VPN

To ping a Layer 3 VPN, use the following command:

ping mpls l3vpn l3vpn-name prefix prefix <count count>

You ping a combination of an IPv4 destination prefix and a Layer 3 VPN name on the egress PE router to test the integrity of the VPN connection between the ingress and egress PE routers. The destination prefix corresponds to a prefix in the Layer 3 VPN. However, the ping tests only whether the prefix is present in a PE router’s VRF table. It does not test the connection between a PE router and a CE router.
