Abstract:
Seamless MPLS design enables a single IP/MPLS network to scale over
core, metro and access parts of a large packet network infrastructure
using standardized IP/MPLS protocols. One of the key goals of
Seamless MPLS is to meet requirements specific to access, including
high number of devices, their position in network topology and their
compute and memory constraints that limit the amount of state access
devices can hold.This can be achieved with LDP Downstream-on-Demand
(LDP DoD) label advertisement. This document describes LDP DoD use
cases and lists required LDP DoD procedures in the context of
Seamless MPLS design.
In addition, a new optional TLV type in the LDP label request message
is defined for fast-up convergence.
