I've been trying to get multicast routing to work on a single 3750G switch between two vlans but for the life of me it just doesn't work. When the host and receiver are on a single vlan the streaming works but then you don't even need multicast routing enabled for it to work. When I split the two hosts onto separate vlans that's where the problem begins. This is what I've configured so far and I'm sure it's just some extra commands I'm missing or something: ip multicast-routing distributed ! ip pim rp-address 3.3.3.3 ! interface Loopback0 ip address 3.3.3.3 255.255.255.255 ! interface GigabitEthernet1/0/1 switchport access vlan 100 ! interface GigabitEthernet1/0/2 switchport access vlan 200 ! interface Vlan100 ip address 1.1.1.2 255.255.255.0 ip pim sparse-dense-mode ! interface Vlan200 ip address 2.2.2.2 255.255.255.0 ip pim sparse-dense-mode ip igmp join-group 239.0.0.1 ! The server streaming via VLC is 1.1.1.1 and is using 239.0.0.1 for the multicast address. The receiver is 2.2.2.1 and using VLC to stream. I can see the traffic coming in on port 1 but no traffic leaving the switch's other port. BTW, I tried dense-mode and sparse-mode as well with similar results. Any thoughts?
