clear ip route necessary after redistribution change?

Unanswered Question
Feb 22nd, 2007

Let's say I have following redistribution configured:

router rip

version 2

redistribute eigrp 1

redistribute ospf 1


default-metric 5

no auto-summary

It works, no problem. Now I change the redistribute statements to contain route map:

redistribute eigrp 1 route-map rip-in

redistribute ospf 1 route-map rip-in

The problem is that the change does not take place until I execute "clear ip route *" on the router (ie. the routes, that are denied by the route map continue to be redistributed).

The question is: is this normal behaviour? Is this manual intervention always necessary?

I have this problem too.

I don't know what's Cisco's recommendation is but I can tell you what my experience has been in this regard. In most situations, any changes that I had made, similar to the one that you did, didn't require clearing the ip routes. There has been one or two situations that I had to manually clear the route(s) for the change to take effect.

I strongly believe the router should recognize the change and effect it without any manual intervention but then there may be bugs in the IOS version that's used. Though, the routes should repopulate quickly on clearing them you have to be careful clearing the routes, especially, if it's a high visibility network.
