Technical Summary
In Ethernet Virtual Private Networks (EVPNs), IP multicast traffic
replication and delivery play a crucial role in enabling efficient
and scalable Layer 2 and Layer 3 services. A common deployment
scenario involves redundant multicast sources that ensure high
availability and resiliency. However, the presence of redundant
sources can lead to duplicate IP multicast traffic in the network,
causing inefficiencies and increased overhead. This document
specifies extensions to the EVPN multicast procedures that allow for
the suppression of duplicate IP multicast traffic from redundant
sources. The proposed mechanisms enhance EVPN's capability to
deliver multicast traffic efficiently while maintaining high
availability. These extensions are applicable to various EVPN
deployment scenarios and provide guidelines to ensure consistent and
predictable behavior across diverse network topologies.
Working Group Summary
Was there anything in the WG process that is worth noting?
For example, was there controversy about particular points
or were there decisions where the consensus was
particularly rough?
This work had broad WG agreement and had good support across multiple vendors
Document Quality
Are there existing implementations of the protocol? Have a
significant number of vendors indicated their plan to
implement the specification? Are there any reviewers that
merit special mention as having done a thorough review,
e.g., one that resulted in important changes or a
conclusion that the document had no substantive issues? If
there was a MIB Doctor, Media Type, or other Expert Review,
what was its course (briefly)? In the case of a Media Type
Review, on what date was the request posted?
This work has intersection with multicast. however all the procedure are limited to scope of BESS working group.
