Conditional policy routing

Is it possible to configure a conditional policy routing?

For example, I want to apply this policy route-map on LAN interface only when WAN interface is up; if WAN is down then don't apply the policy.

Re: Conditional policy routing

Depending on which IOS version you have this might just be possible to achieve through policy based routing coupled with the enhanced object tracking feature. The following link will help you get started.

Re: Conditional policy routing

Thanks for the info, but we are running 12.2 and might not going to 12.3 for a while.

I was trying to use set tag / match tag in route-map but it was not working...

Where I can find detail info for set tag, match tag and match interface?

Re: Conditional policy routing

As far as i know the set tag and match interface commands will not give you what you need (track an interface). Tags are usually used to 'color' routes to be able to apply some policy to them, for example, only to redistribute routes with tag red into ospf. If you can specify the exact details of what you are trying to achieve we might be able to help further.
