Problem Multicast Routing ASA - Catalyst 3750

[martinez.david2]

I meet a traffic multicast problem with 2 firewall ASA and a catalyst 3750. The schema which I reached with the message, is clear to understand met problem. Traffic multicast does not work between local posts IP and distant posts IP.Of course traffic does not pass across the tunnel IPSec. I performed many tests, addition of mroute, displacement of the rdv point, activation of function to bidir, etc..

Thanks a lot for your help,

Appearently you have drawn the ASA-BE-SPO in the wrong direction.

I noticed a difference in the access-lists on the WAN-side for both ASA's.

ASA-VLD allows traffic from 10.100.0.0 255.255.254.0, this is required for the multicast traffic to operate.

In the other ASA, there is no entry for traffic with a source of 10.100.0.0.
