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

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

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,

Hi,
Maybe you are looking for
ping vrf MyVRFname 10.1.1.1
traceroute vrf MyVRFname 10.1.1.1
assuming the customer IP 10.1.1.1 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!
