I do have 7609, 6509 with 2 48 port line card, fwsm & idsm, L2 switches, IronPort Web & Mail security, ASA 5550 & 2821 Roter.
This is for a small ISP network where all external links will be terminated into 6509 RJ-45 line card. In Router 3 links will be terminating with BGP being implemented.
There are some web servers, mail servers etc.
My question is: how to design the network. Shall i connect 7609 directly with 6509? Then where to keep the ASA.What would be the config for BGP in router????
