Backup Routing Problem

Hello NG



I'm an Newbee with Routing and i have an Question about using Backup- Route



Following Problem :



2 Locations, connected with an WiFi Link, both side Cisco 3750. Each location also connected via VPN to Location 3. VPN Routing work's perfectly. Now i have to setup the WiFi Connection between Router A and B. VPN will be used for Backup then.

Router A



172.27.45.1/24 IP Route
0.0.0.0/0 172.27.45.254
172.27.70.0/24 172.27.45.2

VPN Gateway 172.27.45.254 WiFi Gateway 172.27.45.2


Router B



172.27.70.1/24 IP Route
0.0.0.0/0 172.27.70.254
172.27.45.0/24 172.27.70.2

VPN Gateway 172.27.70.254 WiFi Gateway 172.27.70.2


Router A connect to Router B by using WiFi Link. In Case WiFi Link is not available Routing have to change to VPN Gateway.



I didn't have any idea how to solve it. Is anyone able to help me ? Thanks in advance Peter



Use a "floating" static. You simply put a metric on the other static route.

ip route 0.0.0.0 0.0.0.0 172.27.45.2 ip route 0.0.0.0 0.0.0.0 172.27.45.254 200

The first on will be used if the WiFi link is up, but if not the second "floating" route via the VPN will be used.

It could be so simple ;-)

Thanks a lot. I will try it out.
