Configuring Forwarding over the MPLS-TE Tunnel
Perform this task to configure forwarding over the MPLS-TE tunnel created in the previous task . This task
allows MPLS packets to be forwarded on the link between network neighbors.
Before You Begin
The following prerequisites are required to configure forwarding over the MPLS-TE tunnel:
•
You must have a router ID for the neighboring router.
•
Stable router ID is required at either end of the link to ensure that the link is successful. If you do not
assign a router ID to the routers, the system defaults to the global router ID. Default router IDs are subject
to change, which can result in an unstable link.
