Our company recently merged with two other companys. Each company has it's own WAN. I would like to install a router in each headquarters to connect the three company's together. Users could then logon to their server and access Exchange and the Interent. I'm not interested in doing any voice over IP at this time. We are also planning on connecting the three headquarters via frame relay. I'm new to Cisco routers. Which model would work the best in this situation. If anyone has any suggestions, I would really appreaciate them. Thanks!
