Abstract

There are situations following LDP session establishment where it would be useful for an LDP speaker to know when its peer has advertised all of the labels from its Label Information Base (LIB). For example, when an LDP speaker is using LDP-IGP synchronization procedures [RFC5443], it would be useful for the speaker to know when its peer has completed advertisement of its IP label bindings. Similarly, after an LDP session is re-established when LDP Graceful Restart [RFC3478] is in effect, it would be helpful for each peer to signal the other after it has advertised all its label bindings.

               Signaling LDP Label Advertisement Completion

Abstract

   There are situations following Label Distribution Protocol (LDP)    session establishment where it would be useful for an LDP speaker to    know when its peer has advertised all of its labels.  The LDP    specification provides no mechanism for an LDP speaker to notify a    peer when it has completed its initial label advertisements to that    peer.  This document specifies means for an LDP speaker to signal    completion of its initial label advertisements following session    establishment.
