How do I setup routes to allow for a secondary route to become active in the event of an issue with a primary route ?
I have two sites, each with two IOS routers.
R1 and R2 are a HSRP pair in the primary site, and R3 and R4 are a HSRP pair in a satellite site.
There is a private link between R1 and R3, and a second private link between R2 and R4.
The attached document shows the current configuration. I want the following two subnets to communicate with each other.
192.168.10.0/24 - on R1 and R2
192.168.12.0/24 - on R3 and R4
These subnets should communicate over the primary link between R1 and R3 under normal circumstances. If that link fails then the traffic between the subnets needs to move to the link between R2 and R4.
Will the ip route entries on each router, as shown in the attached document, produce the desired affect ?
If not, what is the preferred/recommended way to achieve this ?
