I'm tring to implement IGMP V2 on a test network with various kind of routers, interconnected with dce-dte cable.
Between two 3600 ( IOS 12.1) the multicast packet is correctly forwarded, but when i try to forward it through 1600 or 2621, with 12.2 IOS each, the packet is not forwarded.
Is IGMP supported on these platforms?
I'm using PIM sparse-dense-mode.
thanks for your answer.
