Hi Ali,
I have read through the draft, i think the procedures is fine for IGMP/MLD
proxy. However, this draft doesn't consider multicast router scenario, better
to be added.
Scenario 1:
An EVPN PE acts as multicast router and runs PIM protocol with the
outside multicast routers.
Scenario 2:
An EVPN PE connects to a multicast router on port1, no IGMP receiver
on the port. The PE sends IGMP/MLD to the multicast router.
In both scenarios, the EVPN PE should announce its role through the extended
route type6 to indicate it connects to a multicast router or acts as multicast
router itself.
Other EVPN PEs having local multicast source should forward the multicast
traffic to the PE announcing multicast router role, the PE announcing multicast
router role should not be pruned for all multicast traffic.
For the PE connecting to a multicast router, it should translate EVPN route
type-6 message to IGMP/MLD message, it's already described in your draft. For
the PE acting as multicast router, it should translate EVPN route type-6
message to PIM protocol, this part has not been covered in your draft, better
to be added.
Thanks,
weiguo
