Anyone know if it is valid to have a Multicast group configured on a Cisco device yet have no traffic for that group? I am seeing some Catalyst 4006 devices with some groups in the IPM table but they have a value of 0 for the ipmRoutePkts. I was wondering how the groups got in there if there were no packets. These are for Group/Src entries with 0.0.0.0 as the src so this should be for any source on the group.
Thanks, Pat
