Do I need to have this enabled on the ethernet ports if they are not
participating in multicast? Only the R6 router has the ip igmp join.

I am having an issue getting this multicast config to work correctly.
Any ideas on what I am missing......
R1 is the hub of a frame relay going to R5 and R6 as the remotes,
running ospf. R1 is configured the mapping agent, and R5 as an RP
(Auto-rp). I am joining to the group 239.6.6.6 <http://239.6.6.6> at
the Ethernet on R6.
When I do a show ip igmp group at R6, I can see the multicast group.
However, I cannot see this group show up at R1 and R6. Any thoughts? I
am starting to think that I have a problem with the software load
12.3(5e). Sorry for the lengthy email. Any help or just direction
would be greatly appreciated.
Any thoughts?
R1......
