I am having an issue with getting Source Specific Multicast to work across a simple network. I would appreciate any help the community can provide.
I have a sender on one routed interface on SW1, a receiver on the same subnet as the sender, a receiver on a routed interface on SW1, and another receiver on a vlan access port (SVI 50) on SW2.
Only the receiver on the same subnet as the sender is able to access the multicast feed.
The sender and receivers are Windows 7 machines running VLC Media Player 2.2.1. Each of the machines has Windows Firewall turned off.
The sender is multicasting RTP / MPEG on 232.100.100.100 port 5004. The file is one of the sample videos that come with Windows 7 - Wildlife.wmv
All receivers are listening to rtp://@232.100.100.100:5004
I have tried this topology without the IGMP snooping capable unmanaged switch. Its only in the topology so I could see at least one receiver play the feed while on the same subnet as the sender.
This is a basic proof of concept lab. The production topology will include dozens of senders and many more receivers so statically mapping them is not an option if it can be avoided.
Please let me know if debugs or configuration changes will help make this work. Again, thanks for any help.
