Hi
When static routes are redistributed with bgpd(8), they are not removed when the
interface used by the static is destroyed.
When an interface is destroyed the routes using this interface are flagged with
RTP_DOWN, this means kroute(6)_find() is not able to find them (inserted with
RTP_STATIC and searched with RTP_STATIC|RTP_DOWN on removal)
Here is a diff to remove the RTP_DOWN flag before searching.
Thoughts ?
