Pinging a Layer 2 Circuit
date_range
23-Nov-23
To ping a Layer 2 circuit, use one of the following commands:
ping mpls l2circuit interface interface-nameYou ping an interface configured for the Layer 2 circuit on the egress PE router.
ping mpls l2circuit virtual-circuit neighbor <prefix> <virtual-circuit-id>You ping a combination of the IPv4 prefix and the virtual circuit identifier on the egress PE router to test the integrity of the Layer 2 circuit between the ingress and egress PE routers.
