I've been reading many posts regarding distributing multicast from one location to another over the internet.
I understand that multicast is difficult as well as limited (if at all possible) over IPSEC site-to-site VPN. It seems the best possible scenario is to create a GRE Tunnel between two layer3 devices which are linked by separate firewalls with an IPSEC site-to-site in between. The GRE Tunnel may then be encapsulated within an IPSec site-to-site VPN.
Ignoring restrictions on bandwidth etc., I would very much appreciate some comments /advice as to whether this would be possible, and if so, what kind of devices would be recommended.
Regarding the devices, I would think the choice of firewalls used is more important than the layer3 devices (just for info, the layer3 devices are planned to be 3750's with Advanced IPServices IOS).
Comments, suggestions & advice welcomed.
