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
networks including high number of devices, device position in network
topology, and compute and memory constraints that limit the amount of
state access devices can hold. This can be achieved with LDP
Downstream-on-Demand (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.
This document is a product of the Multiprotocol Label Switching Working Group
of the IETF.
This is now a Proposed Standard.
