The IESG has received a request from the Multiprotocol Label Switching WG
(mpls) to consider the following document:
- 'Using Multipoint LDP when the Backbone has no Route to the Root'
<draft-ietf-mpls-mldp-recurs-fec-03.txt> as a Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf@ietf.org mailing lists by 2011-07-11. Exceptionally, comments may be
sent to iesg@ietf.org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.
Abstract
The control protocol used for constructing Point-to-Multipoint and
Multipoint-to-Multipoint Label Switched Paths ("MP LSPs") contains a
field that identifies the address of a "root node". Intermediate
nodes are expected to be able to look up that address in their
routing tables. However, if the route to the root node is a BGP
route, and the intermediate nodes are part of a BGP-free core, this
is not possible. This document specifies procedures which enable a
MP LSP to be constructed through a BGP-free core. In these
procedures, the root node address is temporarily replaced by an
address that is known to the intermediate nodes and is on the path to
the true root node.
