Currently I have four blocks of IP's: 80, 81, 82, and 83.
I have two T-1 lines coming into one router with two serial interfaces. One t-1 line each. I have already told my ISP to only route traffic to 80 and 81 to serial0 and 82 and 83 to serial1. How do I do the same on my end? I want all traffic from 80 and 81 to use serial0 and 82 and 83 to use serial1.
I've tried using access-lists, but that seems to slow down internet connection. Do I need route-maps? Any help would be greatly appreciated. Thanks.
