Hello,

I need some help. Does anyone has an example of a TCL script for a cisco 1800 series running ios 12.4 how can switch between interfaces if one fails

To be more specific, i have 2 ISP configured on 2 Fast Ethernet ports.
If one fails i want the ip route to switch to the other interface.
I don`t want to manually switch ip route 0.0.0.0 0.0.0.0 fast ethernet...

Thanks in advance !

Hmm

You are saying that if the interface fails

What about makeing 2 0.0.0.0 routes, 1 for each interface. List one of them a higher local preff. And when the interface goes down it will remoe the route that belongs to the interface.

You must know that TCL is unsupported and it is a big risk for the IOS.

An other way is to do an IP SLA ping from the interface to the gateway.. if the ping fails then execute shut on the interface.

The secondary default route with a higher metric would be the easiest solution, at least IMO.
