freebsd stable - Jun 2005 - Routes not deleted after link down

Hi,

i discovered that routes are not deleted from routing table after
link on interface goes down. For example:
> netstat -rnf inet | grep bge0
default            10.1.14.1          UGS         0   135968   bge0
10.1/17            link#1             UC          0        0   bge0
> route -n monitor
got message of size 96 on Sat Jun 18 15:10:38 2005
RTM_IFINFO: iface status change: len 96, if# 1, link: down,
+flags:<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST>
> netstat -rnf inet | grep bge0
default            10.1.14.1          UGS         0   136011   bge0
10.1/17            link#1             UC          0        0   bge0

Should't all routes via bge0 be deleted after link on bge0 goes down?

thanks

Maybe.  If the system was not going to be reconnected to that network anytime 
soon, it would be a good idea.  On the other hand, if the link down was due to 
a transient failure of a wireless connection, which will be back up in a second 
or two, it's much better not to drop the route and kill any open
connections.
