Configuring the Bandwidth Model

You must configure a bandwidth model on all routers participating in the differentiated services domain. The bandwidth models available are MAM, extended MAM, and RDM:

• MAM—Defined in Internet draft draft-ietf-tewg-diff-te-mam-03.txt.
• Extended MAM—A proprietary bandwidth model that behaves much like standard MAM. If you configure multiclass LSPs, you must configure the extended MAM bandwidth model.
• RDM—Makes efficient use of bandwidth by allowing the class types to share bandwidth. RDM is defined in Internet draft draft-ietf-tewg-diff-te-russian-05.txt.

To configure a bandwidth model, include the bandwidth-model statement and specify one of the bandwidth model options:

bandwidth-model {

    extended-mam;

    mam;

    rdm;

}

You can include this statement at the following hierarchy levels:

• [edit protocols mpls diffserv-te]
• [edit logical-routers logical-router-name protocols mpls diffserv-te]
  

  NOTE: If you change the bandwidth model on an ingress router, all the LSPs enabled on the router are taken down and resignaled.
