Configuring Layer 2 tracemroute on a VRF
Use this procedure to configure the Layer 2 tracemroute on the VRF (Layer 3). This procedure
queries the SPBM multicast module to determine the B-VLAN, I-SID and nickname for the S and G
streams. The nickname and I-SID are used to create a multicast MAC address.
Note:
• In the current release, troubleshooting using ping and traceroute (including Layer 2 ping
and Layer 2 traceroute) is not supported on EDM. As an alternative, use the ACLI.
• If you want to run a Layer 2 tracemroute on a VRF, make sure you are in the proper VRF
context.
See the following procedure to perform a Layer 3 tracemroute on a VLAN Configuring Layer 2
tracemroute on a VLAN on page 214.
Before you begin
On the source and destination nodes, you must configure a CFM MD, MA, and MEP, and assign a
nodal MEP to the B-VLAN.
