Configuring the multicast router port time-out value sets the IGS router port-purge time-out value, after which the port gets deleted if no IGMP router control packets are received. Before you can configure IGS features, you must configure your network environment, as described in Topology Example.
SEFOS# configure terminal SEFOS(config)# ip igmp snooping mrouter-time-out 60 SEFOS(config)# end
Dynamically learned mrouter entries are deleted after 60 seconds.
SEFOS# show ip igmp snooping globals Snooping Configuration ----------------------------- IGMP Snooping globally enabled IGMP Snooping is operationally enabled IGMP Snooping Enhanced mode is disabled Transmit Query on Topology Change globally disabled Multicast forwarding mode is MAC based Proxy globally disabled Proxy reporting globally enabled Filter is disabled Router port purge interval is 60 seconds Port purge interval is 260 seconds Report forward interval is 5 seconds Group specific query interval is 2 seconds Reports are forwarded on router ports Group specific query retry count is 2 Multicast VLAN disabled Leave config level is Vlan based
Statically configured router ports are not deleted after the expiration of the router purge-time interval.
