EVPN multicast route (multi home case ) implementation / deployment information

Tue Feb 4 16:59:13 UTC 2020

Hi Mankamana,

For Juniper:

Starting in Junos OS 18.4R1, devices with IGMP snooping enabled use 
selective multicast forwarding in a centrally routed EVPN-VXLAN network 
to replicate and forward multicast traffic. As before, IGMP snooping 
allows the leaf device to send multicast traffic only to the access 
interface with an interested receiver. But now, when IGMP snooping is 
enabled, the leaf device selectively sends multicast traffic to only the 
leaf devices in the core that have expressed an interest in that 
multicast group. In selective multicast forwarding, leaf devices always 
send multicast traffic to the spine device so that it can route 
inter-VLAN multicast traffic through its IRB interface.

Kind regards,
Andrey
