Enabling Proxy downstream interface
Enable MLD mroute proxy on the interface in which the interface is in the direction contrary to the root of the multicast forwarding tree. In this example eth2 is the downstream interface which is connected to receiver.
#configure terminal | Enter Configure mode. |
(config)#interface eth2 | Enter Interface mode |
(config-if)#ipV6 address 3000::1/64 | Assign IPv6 address to an interface |
(config-if)#ipv6 MLD mroute-proxy eth1 | Enable MLD mroute proxy on the downstream interface and specify the upstream proxy interface name. |
(config-if)#commit | Commit the transaction. |
(config)#exit | Exit Configure mode. |
