Multicast Cisco and Avaya

[mohashim]

I hv Avaya P882 as core,Cisco cat4507 as distribution and cat3750 access. There are a video in Avaya P882 configure multicast. PC attach to Avaya can receive video stream but PC at Cisco cat4507 and cat3750 cannot receive video stream from avaya P882. my understanding avaya P882 only support DVMRP. Any advice how to configure on Cat4507 and Cat3750. did i need ip mroute?

you can configure IOS to use DVMRP for interoperability between systems.

please see the following link for more DVMRP interoperability and configuration info:
