Stub Multicast Router on ASA

Hi,

I'm swapping out a PIX, IOS 6.3 with an ASA 5520 v8. The PIX has the following 2 commands in it's config:

multicast interface outside

multicast interface inside

These commands do not exist on the ASA. I do not wish to enable multicast routing. What commands on the ASA are equivalent to the multicast commands on the PIX?

Thanks

Yolande

Re: Stub Multicast Router on ASA

hostname(config-if)#igmp

hostname(config-if)#igmp forward interface outside

This will enable the inside interface for IGMP forwarding and configure

all multicast requests coming from the inside interface and forward them

to the outside.

This should be it, remember to remove all your PIM configurations as PIM

and IGMP Stub Multicast Routing are not simultaneously supported.

The Cisco TAC has written an ASA Multicast troubleshooting guide that might help other engineers that run into multicast problems:
