Creating an MPLS-TE Tunnel
Creating an MPLS-TE tunnel is a process of customizing the traffic engineering to fit your network topology.
Perform this task to create an MPLS-TE tunnel after you have built the traffic engineering topology.
Before You Begin
The following prerequisites are required to create an 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.
•
If you are going to use nondefault holdtime or intervals, you must decide the values to which they are
set.
