[cisco-voip] SLP -- Multicast? Berbee IP Speakers across wan

Wed Sep 17 13:48:54 EDT 2008

The problem I'm running into is that IC and IP speakers are both using SLP.
each is mulitcasting 239.255.255.253.  since both are multicasting that
address the router will not forward the multicast to the other interface.
so then I have to setup Source specific Multicasting to get the traffic
through.  Not wanting to setup more stuff to admin on each location.
