A few seconds later:-
CORE2#sh ip mfib 192.168.31.10 239.199.3.1 Packets: 2542018/0/1, Bytes: 620905501/0/311
So we are sending traffic.
On the other end of Vlan 30 is:-
CORE1#sh ip mfib 192.168.31.10 239.199.3.1 IP Multicast Forwarding Information Base Entry Flags: C - Directly Connected, S - Signal, IC - Internal Copy Interface Flags: A - Accept, F - Forward, S - Signal IC - Internal Copy, NP - Not Platform fast-switched Packets: Fast/Partial/Slow Bytes: Fast/Partial/Slow (192.168.31.10, 239.199.3.1), flags () Packets: 11/0/0, Bytes: 3495/0/0 Vlan64 (F S) Vlan30 (S) Vlan32 (F S) CORE1#
This one has NO "Interface Flags: A - Accept" interface.
We look OK as far as I can see but it is NOT working.

Each (routing) interface has:-
ip pim query-interval 1 ip pim sparse-mode
We are also for some reason running msdp between all of the 7 routers in a full mesh although we have only a single ospf area.
I tried clear ip mroute 239.199.3.1 on Core1.
Ideas?
