Configure Dynamically Learned Multicast Router Port Time-Out

Configuring the MLDS router purge time-out deletes the dynamically learned multicast router ports if no MLD router control packets are received. Use the mrouter-time-out command to set the aging-out time after multicast router ports are dynamically learned, as shown in the following example.

The default value for the multicast router port time-out is 125 seconds. This example configures the value as 60. Dynamically learned router entries will be deleted after 60 seconds.

1. Configure the multicast router port time-out value.

   SEFOS# configure terminal
   SEFOS(config)# ipv6 mld snooping mrouter-time-out 60 
   SEFOS(config)# end

2. View the configuration.

   SEFOS# show ipv6 mld snooping globals
