Dear All,
We would like to kick start discussions on the multicast draft -
https://datatracker.ietf.org/doc/draft-ghanwani-nvo3-app-mcast-framework/
>From Section 3.2 "Replication at the source NVE"
>> When a VPN client has multiple multicast groups, [RFC6513]
"Multicast VPN" combines all those multicast groups within each
VPN client to one single multicast group in the MPLS (or VPN)
core. End result: All messages from any multicast groups
belonging to one VPN client will reach all the PE nodes of the
client. I.e. any messages belonging to any multicast groups under
Client XX will reach all PEs of the Client XX. When the Client XX
only has a handful of PEs, there is not too much bandwidth wasted
in the core.
One way to address this issue is to use replication at source NVE which will
make sure that the multicast traffic will get delivered only to those NVEs
where there are members; multicast groups don't get combined in any way. Are
there other ways of addressing this issue? Comments on this topic or other
comments on the draft would be much appreciated.
Thanks,
Ramki
