The current LDP Graceful Restart (GR) mechanism specified in RFC3478
requires a complete re-advertisement of the LDP label binding
information across a session restart, even though complete label
binding information might be preserved.
In this document we specify extensions to LDP graceful restart in
order to support avoiding unnecessary transmission of the label
binding information preserved across a session restart, thus
accelerating the router re-convergence. More specifically, we
describe a version number based batching mechanism for keeping track
of the label binding information across a session restart.
The new 1) LDP ILA capability TLV, 2) LDP VERSION ID TLV and 3) LDP
ILA Version message type, is introduced for checkpointing the label
binding version maintained for a neighbor. We also specify
procedures for handling label binding table version update across a
session restart.
