Where do I start, this little issue has been giving me a headache!
We have a requirement for phone calls internal to internal to stream Music on Hold from the Local Flash.
We have -
1 x 2811 Router, with Multicast Routing enabled and ip pim sparse mode on loopback 0 and interface FastEthernet 0/1
1 x 3750 L3 Switch , with Multicast Routing enabled and ip pim sparse mode on VLAN facing Router and VLAN that has phones. (SVI's on switch)
For basic testing i wanted to see if Multicast works on the LAN with nothing configured, so we had one PC in one VLAN sending to 188.8.131.52 (TTL = 1) and a PC is another VLAN listening on 184.108.40.206 and it works across layer 3 switch.
So my problem, am I configuring multicast correctly?
My traffic flow I believe is Phone listens to 220.127.116.11, switch has this in its mroute table, forwards request to router, router starts sending MoH to 18.104.22.168.
Has anyone been able to get this working? Hopefully this is understandable, I only just started to understand Multicasting.
Any imput would be appreciated.
