MPLS trace and Ping

How to make trace and ping are available in MPLS PE router? Can I ping or trace a customer IP from the PE router?

Re: MPLS trace and Ping

This functionality has been available since 12.0(27)S.

Please refer to the Cisco Feature Navigator to find out which other IOS releases and platforms it is supported on:

Check for this specific feature:

MPLS LSP Ping/Traceroute and AToM VCCV

Cisco Feature Navigator:

As to your other question, you can generally ping and traceroute to the customer network from the PE provided that the address you are using for the ping/traceroute is present in the VRF of the specific PE. This would exclude MPLS ping and traceroute thoug, if this is what you are asking.

Hope this helps,

Re: MPLS trace and Ping


Maybe you are looking for

ping vrf MyVRFname

traceroute vrf MyVRFname

assuming the customer IP is reachable through VRF MyVRFname. You also can use the extended ping and extended traceroute options, when pressing "enter" after the VRF name.

Without the "vrf MyVRFname" portion, ping and traceroute will use the global IP routing table, which should NOT contain customer IP addresses. Hence the ping/traceroute will fail unless you have address overlapp.

Hope this helps!
