Abstract:
EVPN supports intra and inter-subnet IP multicast forwarding.
However, EVPN (or conventional IP multicast techniques for that
matter) do not have a solution for the case where the following two
statements are true at the same time: a) a given multicast group
carries more than one flow (i.e., more than one source), and b) it is
desired that each receiver gets only one of the several flows.
Existing multicast techniques assume there are no redundant sources
sending the same flow to the same IP multicast group, and, in case
there were redundant sources, the receiver's application would deal
with the received duplicated packets. This document extends the
existing EVPN specifications and assumes that IP Multicast source
redundancy may exist. It also assumes that, in case two or more
sources send the same IP Multicast flows into the tenant domain, the
EVPN PEs need to avoid that the receivers get packet duplication by
following the described procedures.
