You can definitely filter with deny statements when redistributing with a route-map. Either a deny in the prefix-list or access-list or a deny sequence in the route-map.

I thought you could use route-maps to filter routes during redistribution. I think I can find some examples of that. Thanks Patrick A.

Subject: Re: [OSL | CCIE_RS] Vol 1 LAB 34 route-map calling a prefix list question Yeah, you're right. I thought you were setting an attribute to the prefix to make the route invalid. I believe the only options you have are using a prefix-list or a distribute-list. A route-map may work if you can set an attribute to the prefix to make it invalid (ie change the AD to 255? I don't know if you can do that or set the next-hop to something not reachable by the peer receiving the route?). If you find a way to do this you're not filtering the route but the neighbor would not put the route in the routing table. Not sure if that would meet the requirement. I don't think route-maps are meant for route filtering.
