Link Manager

Underneath a lot of externally visible RSVP and MPLS things is something called the link manager. The link manager's job is to track interface-related stuff with regard to MPLS Traffic Engineering. Specifically, the link manager keeps track of the following:

  • Flooding— What information to flood and when to flood it

  • Admission control— When an RSVP message comes in, whether to allow it or deny it

The link manager isn't really something you can configure. However, it's useful to know it's there.

The link manager has several things you can look at, as demonstrated in Example 4-45.
