EIGRP static route metric

Craig Rees
Level 1
Level 1

Is it possible to redistribute a static route into EIGRP and give it a higher or lower metric.

I have two locations with a circuit at each location going to a single remote location. I want to advertise static routes via EIGRP to the remote location and have the remote location use different remote locations depending on the metric it recieves. If one of the locations goes down have the remote location send all traffic to the one location still up.

I am not sure that I understand very well what your requirements really are. But there are several alternatives which may give you the results that you need.

When you redistribute static routes into EIGRP you must specify a default metric. So you might specify a default metric in location A including delay 100 (for example) and in location B specify a default metric including delay 1000. Both A and B would advertise their routes to the remote. The result would be that static routes from A would be more attractive but if location A became unavailable then the routes from location B would be usable.

Another alternative to consider is that you can control redistribution with a route map. In the route map you could set the metric to one value (delay 100) for one grouop of routes and set the metric to a different value (delay 1000) for a different group of routes. And at location B you would set some other value of the metric. This would be especially useful if you want some routes from A to be most attractive and some other routes from B to be most attractive.

Another alternative to consider is the possibility of using an offset list. You configure an offset list in EIGRP associated with an interface. The function of an offset list is to add some incremental value to the metric of routes being advertised. One possibility in the offset list is to refer to an access list. This gives you the ability to increment the value for some routes and not for other routes. So if you want all routes from location A to be more attractive you would configure an offset list at location B on its link to the remote site and in the offset list at B you add some amount to the metric. And if you want some routes from A to be best and some other routes from B to be best then you would configure an offset list at A with an access list to selectively make some of its routes higher metric and some not. And you would configure an offset list at B with an access list to selectively make other routes higher metric.

Hopefully one of these alternatives will do what you want. If not please clarify what your requirements are and we will see what we can suggest.
