Configure a Static Multicast Router Port

The ipv6 mld snooping mrouter command statically configures the router ports for a specified VLAN.

In this example, VLAN 4 is the VLAN for which the snooping version is configured, and the multicast router ports are 0/4 and 0/5.

1. Specify a static configuration for the multicast router ports.

   SEFOS# configure terminal
   SEFOS(config)# vlan 4
   SEFOS(config-vlan)# ipv6 mld snooping mrouter extreme-ethernet 0/4
   SEFOS(config-vlan)# ipv6 mld snooping mrouter extreme-ethernet 0/5
   

2. View the configuration.

   SEFOS# show ipv6 mld snooping mrouter
    
   Vlan   Ports
   -----  ------
     4   Ex0/4(static), Ex0/5(static)
   

3. Send an MLD v1 query message on port 2.
4. View the configuration in switch A.

   SEFOS# show ipv6 mld snooping mrouter
    
   Vlan   Ports
   -----  ------
       4  Ex0/2(dynamic), Ex0/4(static), Ex0/5(static)
   

   Note that router ports will also be learned when they receive a PIM/OSPF message from a router.
