Trigger a Layer 2 Tracetree
Use this procedure to trigger a Layer 2 tracetree. Layer 2 tracetree allows a user to trigger a multicast LTM message by specifying the B-VLAN and I-SID. The command allows the user to view a multicast tree on the SPBM B-VLAN from the source node to the destination nodes for a particular I-SID.
Before you begin
-
On the source and destination nodes, you must configure a CFM MD, MA, and MEP.
-
Enable the MEP.
-
Assign a nodal MEP to the B-VLAN.
