Question : Failover internet routing advice

Hi,

Just hoping for a bit of advice here.

- We have two sites connected be dedicated leased lines with Cisco 2811 routers.
- Each site also has there own internet connection using Cisco ASA 5510
- The clients use the routers as there default gateways.
- Both routers have RIP v2 setup for both 192.168.4.0 and 192.168.5.0.
- Each router also has a default router pointing to their own ASA.

What I would like to do is add a bit more redundancy to the connection by adding a extra routes on each router to point to the other sites ASA as a backup.

example for site A would be
from:

router rip
 version 2
 network 192.168.5.0
 network 192.168.6.0
 no auto-summary
route 0.0.0.0 0.0.0.0 192.168.5.1

to:
router rip
 version 2
 network 192.168.5.0
 network 192.168.6.0
 no auto-summary
route 0.0.0.0 0.0.0.0 192.168.5.1 10
route 0.0.0.0 0.0.0.0 192.168.4.1 20

I would like some advice to configure the routers to have a better fail over for the internet connection like a ip sla with a ping or something along those lines.

Any advice would be greatly appreciated.

I would setup an ip sla policy on each router. This link should get you started: https://dakeung.com/2009/07/03/cisco-dual-wan-fail-over-using-sla-tracking/

Configure one side, than mirror it on the other side

Good Luck
