372CHAPTER 18: CONFIGURING AND MANAGING IGMP SNOOPING

Enabling Router A WX switch can search for multicast routers by sending multicast router

Solicitation solicitation messages. This message invites multicast routers that receive the message and that support router solicitation to immediately advertise themselves to the WX switch. Router solicitation is disabled by default.

The MSS 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]

Changing the Router The default multicast router solicitation interval is 30 seconds. To change Solicitation Interval the interval, use the following command:

set igmp mrsol mrsi seconds [vlan vlan-id]

You can specify 1 through 65,535 seconds. The default is 30 seconds.

Configuring Static A WX switch learns about multicast routers and receivers from multicast

Multicast Ports traffic it receives from those devices. When the WX switch receives traffic from a multicast router or receiver, the switch adds the port that received the traffic as a multicast router or receiver port. The WX switch forwards traffic to multicast routers only on the multicast router ports and forwards traffic to multicast receivers only on the multicast receiver ports.

The router and receiver ports that the WX switch learns based on multicast traffic age out if they are unused.

You can add network ports as static multicast router ports or multicast receiver ports. Ports you add do not age out.

You cannot add MAP access ports or wired authentication ports as static multicast ports. However, MSS can dynamically add these port types to the list of multicast ports based on multicast traffic.
