Im trying to enable multicasting on our network for ghosting.
We are using a 4507R as our router and 3750 for our access switches.
I have enabled IP multicast-routing and ip pim sparse-dense-mode on the affected VLAN interface's on the 4507.
I havent changed the default multicast settings on the 3750's
Ghostcast will not work and I presume I have not properly configure multicast routing.
the 3750's are running the base IP IOS
how should I best configure my hardware to enable multicasting.
