Multicast over lan to lan ipsec tunnel

[navypop42]

I need to configure multicast between 2 Csico 5540's lan to lan ipsec tunnel for a Voip application. Is this possible and what is a reccomended configuration example?

Hi,

You will not be able to pass mcast traffic over pure IPsec tunnel.

Suggested solution is to add GRE between two routers behind ASAs and provide protection via IPsec for this GRE on ASA.
