new import map in existing VRF

[xameslin]

Hello,

On my PE, I defined a VRF. My VRF contains routes. Now, I want to create/modify a import map to filter/modify some routes. All new routes will pass through the new import map but not old ones. How can I do to reapply this route-map to all existing routes with the lowest impact ?

I know some commands to do it, but I'm looking for the best one for a live network.

For example, I perform following command :

no route-target import X:Y and route-target import X:Y but I'm not sure it's the best one. It's worked.

Rgds,

Xavier

cant you issue something similar to clear ip bgp * soft

doesn't seem to work.

But actually I think it's automatic without any command. The bgp scan-time IMPORT timer seems to do the job.
