Are you talking about the perimeter routers? so the routers are conencted to different providers. right? and you want to load balance or have redundancy between the routers and the ASA firewalls?

Ok. Because the routers are not routing to the same destination, (internet) the only redundancy you will have is on the ASA level because only one router is used for internal routing to the DR site while the other is routing externally to the internet. You can setup the ASA's in Active/standby mode and only one is active and the other is standby to take over if the active fail. Setup your switches (C3750) to use the active ip address on the ASA's as the default gateway as well as your DMZ External servers. On the ASA's setup a default route to the perimeter internet router for internet connection and a static router to your DR site.

Are your C3750 switches stacked? Looks like you don't have any connection between those switches!!

i am making sense?

Hi, Francisco,

Thanks for the reply,I would like to go in for active active config for ASA ,and i would be stacking both the 3750 also what are the other options to have this implemented .
