Chapter 25: WAN Configuration Guide
Multi-Router WAN Configuration
The following is a diagram of a multi-router WAN configuration encompassing three
subnets. From the diagram, you can see that R1 is part of both Subnets 1 and 2; R2 is part
of both Subnets 2 and 3; and R3 is part of subnets 1 and 3. You can click on the router label
(in blue) to jump to the actual text configuration file for that router:
