Title : Propagation of VPLS IP Multicast Group
Membership Information

The PEs participating in VPLS need to learn the IP multicast group
membership information from remote VPLS sites to enable them to send
an IP multicast packet to only those other PEs in the VPLS that have
receivers interested in that particular IP multicast packet's
multicast source and group. This document describes procedures for
propagating multicast control information, learned from local Virtual
Private LAN Service (VPLS) sites, to remote VPLS sites. IGMP or PIM
snooping is required only on the customer facing interfaces. The
procedures do not require IGMP or PIM snooping on the Service
Provider backbone links. Instead they use reliable protocol messages
to exchange multicast control information between the PEs.

In the body type:

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
