I am currently setting up and MPLS WAN on a private connection between my branches and corporate hq. Currently we are using VPN through a pix. I would like to put the routers in series and set up a system of routing to differentiate WAN and internet routes. This is how I envision it set up
LAN ---> Cisco 2801 ----> Dual T1 (multilink) MPLS (2 serial interfaces) -----> Branch (Cisco 2801 10.1.xx.xx)
Cisco Pix 515 -------> Cisco 2621 -----> internet and Branch Cisco 1721 10.2.xx.xx
How do I set up routes on the Cisco 2801 to direct outgoing traffic on my LAN that is destined for 10.1.xx.xx to go out the multilink interface on the 2801 router and 10.2.xx.xx as well as all internet traffic to go out the serial interface on the 2621 router as I will still be retaining a few VPN tunnels? Thank you in advance for any help and please request further information if necessary.
