Enabling Router Solicitation A switch 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 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 Solicitation Interval The default multicast router solicitation interval is 30 seconds. To change 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 Multicast Ports A DWS-1008 switch learns about multicast routers and receivers from multicast traffic it receives from those devices. When the 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 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 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. Note: You cannot add 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. D-Link DWS-1008 User Manual 219
