Prerequisites for Implementing Multipoint Layer 2 Services
Before configuring Multipoint Layer 2 Services, ensure that these tasks and conditions are met:
• You must be in a user group associated with a task group that includes the proper task IDs. The command
reference guides include the task IDs required for each command.
If you suspect user group assignment is preventing you from using a command, contact your AAA
administrator for assistance.
• Configure IP routing in the core so that the provider edge (PE) routers can reach each other through IP.
• Configure a loopback interface to originate and terminate Layer 2 traffic. Make sure that the PE routers
can access the other router's loopback interface.
The loopback interface is not needed in all cases. For example, tunnel selection
does not need a loopback interface when Multipoint Layer 2 Services are directly
mapped to a TE tunnel.
Note
• Configure MPLS and Label Distribution Protocol (LDP) in the core so that a label switched path (LSP)
exists between the PE routers.
