Changing Robustness; Enabling Router Solicitation - Nortel 2360 Configuration Manual

Changing robustness

Robustness adjusts the IGMP timers to the amount of traffic loss that occurs on the network. Set the robustness value
higher to adjust for more traffic loss. To change the robustness value, use the following command:
set igmp rv num [vlan vlan-id]
You can specify a value from 2 through 255. The default is 2.

Enabling router solicitation

A WSS can search for multicast routers by sending multicast router solicitation messages. This message invites
multicast routers that receive the message and that support router solicitation to immediately advertise themselves to the
WSS. Router solicitation is disabled by default.
The WSS Software implementation of router solicitation is based on draft-ietf-idmr-igmp-mrdisc-09.txt.
To enable or disable multicast router solicitation, use the following command:
set igmp mrsol {enable | disable} [vlan vlan-id]
