Configuring Multicast on 3560

Ihave a 3560 w/multicast support and I'm trying to configure a simple environment. I have 2 ports configured, one for the multicast server and the other for the client. Each are on their own subnet, so I have an ip route between the two. My run config on both ports is:

ip multicast-routing distributed

interface fastethernet 0/3 & 0/4

ip pim version 2

ip pim sparse-dense-mode

I'm using vlc server /client configured to use 224.0.0.1 on my isolated network. I can see the mulitcast traffic going into the port, and I the client is sending reports, but I think the 3560 is dropping the packets, since I don't see them coming in the client port. any suggestion on configuing a simple multicast environment using 2 ports on a Cisco 3560 would be very appreciated.

Thanks

Yes, remove the following:

ip multicast-routing distributed

ip pim version 2

just enable:

ip multicast-routing

also, I am assuming fa0/3 and fa0/4 are both L3 interfaces, if not you need to put the pim commands on the L3 interface.

show ip mroute >>>>> do you see the s,g?

show ip igmp >>>> do you see the client's igmp join?

Re: Configuring Multicast on 3560

Any updates on this?

I'm using AirPlay on Apple iOS and Apple TV devices.

I've setup:

ip multicast-routing distributed

on a 3560 running IP Services and on the two vlans:

ip pim sparse-dense-mode

I'm able to see the Apple TV devices while on the same subnet, but once I switch to the other subnet, the devices are no longer visible.

Any suggestions?

Thanks

Re: Configuring Multicast on 3560

Hi,

I'm using vlc server /client configured to use 224.0.0.1

The 224.0.0.0-224.0.0.255 range is not routeable( ttl= 1).

Regards.

Alain.
