I've moved the configuration on the switch so that the ports are routed now instead of using vlans but still no go.
Here is the output from a show ip mroute: Switch#sh ip mroute IP Multicast Routing Table 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, z - MDT-data group sender, Y - Joined MDT-data group, y - Sending to MDT-data group V - RD & Vector, v - Vector Outgoing interface flags: H - Hardware switched, A - Assert winner Timers: Uptime/Expires Interface state: Interface, Next-Hop or VCD, State/Mode (*, 239.255.255.250), 00:01:03/00:02:56, RP 3.3.3.3, flags: SJC Incoming interface: Null, RPF nbr 0.0.0.0 Outgoing interface list: GigabitEthernet1/0/2, Forward/Sparse, 00:01:03/00:02:06 GigabitEthernet1/0/1, Forward/Sparse, 00:01:03/00:02:56 (*, 239.0.0.1), 00:01:22/00:02:56, RP 3.3.3.3, flags: SJCL Incoming interface: Null, RPF nbr 0.0.0.0 Outgoing interface list: GigabitEthernet1/0/2, Forward/Sparse, 00:01:23/00:02:56 (*, 224.0.1.40), 00:01:23/00:02:08, RP 3.3.3.3, flags: SJCL Incoming interface: Null, RPF nbr 0.0.0.0 Outgoing interface list: Loopback0, Forward/Sparse, 00:01:23/00:02:08 Switch# Switch#sh ip pim interface Address Interface Ver/ Nbr Query DR DR Mode Count Intvl Prior 3.3.3.3 Loopback0 v2/S 0 30 1 3.3.3.3 1.1.1.2 GigabitEthernet1/0/1 v2/S 0 30 1 1.1.1.2 2.2.2.2 GigabitEthernet1/0/2 v2/S 0 30 1 2.2.2.2 Switch# The traffic is still coming in on port 1: Switch#sh int g1/0/1 GigabitEthernet1/0/1 is up, line protocol is up (connected) Hardware is Gigabit Ethernet, address is 0018.73bf.12c1 (bia 0018.73bf.12c1) Internet address is 1.1.1.2/24 MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, reliability 255/255, txload 1/255, rxload 12/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 100Mb/s, media type is 10/100/1000BaseTX <snip> 30 second input rate 4822000 bits/sec, 444 packets/sec 30 second output rate 0 bits/sec, 0 packets/sec but not exiting on port 2 Switch#sh int g1/0/2 GigabitEthernet1/0/2 is up, line protocol is up (connected) Hardware is Gigabit Ethernet, address is 0018.73bf.12c2 (bia 0018.73bf.12c2) Internet address is 2.2.2.2/24 MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 1000Mb/s, media type is 10/100/1000BaseTX <snip> 30 second input rate 4000 bits/sec, 6 packets/sec 30 second output rate 1000 bits/sec, 1 packets/sec I've changed the TTL on VLC to 10 and I've also changed things to sparse-mode and put it on the loopback as well.
