Hi Folks,
I'm having some issues with multicast routing - though it certainly wouldn't be my strongest area of networking expertise so it may be something simple. I have two sources for group 239.192.255.3 on two VLANs (43, 10.4.43.28 and 943, 192.168.43.28) and a destination upstream (out interface tengigabit 1/2 - which is also a source for the same group at the same time 10.1.32.32).
The following shows the multicast route table for this group.

Flags: D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected,
L - Local, P - Pruned, R - RP-bit set, F - Register flag,
T - SPT-bit set, J - Join SPT, M - MSDP created entry,
X - Proxy Join Timer Running, A - Candidate for MSDP Advertisement,
U - URD, I - Received Source Specific Host Report, Z - Multicast Tunnel
Y - Joined MDT-data group, y - Sending to MDT-data group
Outgoing interface flags: H - Hardware switched, A - Assert winner

I can't figure out why (10.4.43.28, 239.192.255.3) is not routed out TenGigabitEthernet1/2 as well as VLAN 943 a imilar to the way that (192.168.43.28, 239.192.255.3) is.
Any suggestions?
Thanks!
