When a BPS or a 460/470 is connected to a multicast router/querier via MLT or SMLT, if the first link in the MLT failed the IGMP reports sent in response to a query were never forwarded out of the second MLT link. (Q01130212). Whenever a specific Mac-Address [08-00-09-A0-75-40] was searched from a VLAN other than its own, it resulted in stack instability (Q01197202-01).
