I have a point-to-point WAN connection connecting site1 to site2. I want to allow multicasts to go from site1 to site2, but want to control what multicast travels down the WAN. My question is will an igmp access group do this for me?
if having ip pim sparse-dense mode on the interfaces traffic for a group not associated to a RP is treated as dense mode and uses a "flood and prune" strategy: it is sent before an explicit join is done.
the ip igmp join-group command using an ACL filters igmp joins from end user PCs so it can limit what sparse mode groups can travel on the link.
I see that you have ip pim sparse-mode so your setup should be effective.
