Verifying an MPLS Layer 2 Circuit Configuration
To verify the connectivity of MPLS Layer 2 circuits, use the ping mpls command. This command helps to verify that the circuit has been enabled by testing the integrity of the Layer 2 circuit between the source and destination routers.
To ping an interface configured for the Layer 2 circuit on the PE router, enter the following command:ping mpls l2circuit interface interface-name
To ping a combination of the IPv4 prefix and the virtual circuit ID on the destination PE router, enter the following command:ping mpls l2circuit virtual-circuitprefix virtual-circuit-id
