Configuring an IETF DS-TE Tunnel Using MAM
Before You Begin
The following prerequisites are required to configure an IETF mode differentiated services traffic engineering
tunnel using the MAM bandwidth constraint model:
• 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
SUMMARY STEPS
1. configure
2. rsvp interface type interface-path-id
3. bandwidth mam {total reservable bandwidth | max-reservable-bw maximum-reservable-bw} [bc0
reservable bandwidth] [bc1 reservable bandwidth]
4. exit
5. exit
6. mpls traffic-eng
7. ds-te mode ietf
8. ds-te bc-model mam
9. exit
10. interface tunnel-te tunnel-id
11. signalled-bandwidth {bandwidth [class-type ct] | sub-pool bandwidth}
12. Use the commit or end command.

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.
