Please look into the attached Diagram. We have got some 3640 routers and 7507 BG router with Public Networks A throuh I as mentioned in the Diagram.
We are looking to introdue a Cisco ASA 5500 into the network for the Public Networks A through E and I and H. Public Networks F and G will not be behind the FW post implmentation.
We are thinking of introducing a Cisco 3560G-24 Switches to do the job.The implementation will also offload the Public Networks F and G from the BG(Border Gateway).
Please give me some inputs on this.
I am little confused on where to place the FW because the Implementation should be a first step for a near future redundant setup in terms of connectivity and HW.
