Multicast over ATM

I Have an ATM WAN Network, I need to carry multicast over IMA interfaces, I have one 3745 and four 2650XM, the 3745 is the central site, the 3745 is connected to one Avaya Cajun Switch, this Avaya has interconnected the multicast host, the Avaya is running DVMRP.

Is possible carry multicast over this network?

Re: Multicast over ATM

Cisco will (used to?) support DVMRP. If you enable multicast routing on the 3745 (global: ip multicast-routing) and configure the multicast parameters (you will not want uncontrolled multicast across the WAN).

Check to see if the Avaya supports PIM (preferably sparse mode) and use that instead. DVMRP (if I recall correctly) is a fairly verbose protocol and/or does not have much ability to control the traffic flow as well as PIM.

Good Luck

Scott
