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
• If you are going to use nondefault holdtime or intervals, you must decide the values to which they are
SUMMARY STEPS
1. configure
2. interface tunnel-te tunnel-id

5. path-option preference - priority dynamic
6. signalled- bandwidth {bandwidth [class-type ct ] | sub-pool bandwidth}
7. Use the commit or end command.
