Abstract:
Ethernet Virtual Private Network (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.
