Route manipulation

I'm injecting static routes into EIGRP.

Is there any way to have a redistributed static route leave the EIGRP routing table when it's no longer use?

Or is there any kind of way for a route to recognize "something" ie another route, vpn or anything and then inject itself into EIGRP?

define "no longer use".

yes, static routes can be subject to tracking objects. That is a last resort configuration however, often there are alternatives.

Belivacua thanks for the reply and disregard my ignorance. I jump the gun and hit me this morning around 2 a.m.! I don't need that route to be redistributed at all, so I just manipulated the acl.


Can you tell me about the tracking objects or point me to a good link?


thx

Hello Eric,


here it is a link to reliable static routing and object tracking


http://www.cisco.com/en/US/docs/ios/12_3/12_3x/12_3xe/feature/guide/dbackupx.html')">http://www.cisco.com/en/US/docs/ios/12_3/12_3x/12_3xe/feature/guide/dbackupx.html


using this feature the state of a static route is subject to the track test you define.


To be noted that a static route can be removed from the routing table even without using this feature when the outgoing interface fails for example.


Redistribution is a dynamic process executed from time to time and so a static route removed from the routing table is going to be removed also from EIGRP updates and database


Hope to help

Giuseppe
