Hi Rob, Did you mean to say you have IGMP static-groups on the 7600_3 to attract multicast traffic toward your distribution switches? If you meant 7600_1 then I'm not sure what your topology is but the redundancy issue made me think of a similar issue I faced in the past. Are you using any

We use IneoQuest gear to monitor multicast data after it leaves the source and before it enters the destination. The boxes give nice reports of both IP and MPEG, and are MDI compliant (RFC4445) Cheers, JF cisco-nsp cisco-nsp-boun...@puck.nether.net a écrit sur 2013-07-16 12:53:23 : De : R S
