Hi, all, I am working on a project to enable multicast for home workers. Most employees have 851W at home and run ezvpn to headquarter ASA. Since ASA does not support DMVPN/VTI therefore mulitcast is not possible, so I plan to move ezvpn headend to a Cisco ISR, when trying to do a POC setup at home, I am surprised to find out that 851W does not even support mulitcast (ip pim command not available)!! I am running c850-advsecurityk9-mz.124-15.T7.bin, is there any other 850 image that supports ezvpn (client only), VTI and multicast? I searched feature navigator, but could not find any. I could not believe it, I thought multicast is just like IP routing, should be built-in in any IOS images. Thanks a lot..

Bascially - if it's not in the feature navigator, then the platform does not support it.
Is there a specific requirement for multicasting - application based?

The application is to run voip over wireless, in order to support voice broadcast/paging functionality, multicast is needed.

Jiang,
It is my understanding that the 851 routers do not support PIM.
You need a minimum of 871 routers to do multicast. Please refer the below URL for details.
