The Indigo access server is enabled for native IP multicast.
To check group membership, it uses IGMP queries. Because it's
a Cisco, PIM is enabled too, so it will accept you as a PIM
neighbour if you're PIM-capable. There isn't anything you can 
do about this. If you want to time yourself out, you need to
modify appropriate filters so that IGMP/PIM traffic is not 
classified as "interesting" traffic.
