I've encountered a nasty, easily reproducable bug in 2.1R that causes
a panic. The following sequence:
route add 200.11.1.17 200.11.1.3
/* where 200.11.1.17 is inactive or doesnt exist and 200.11.1.3 is
another FreeBSD router/host on the network. It creates a route entry
Dest=200.11.1.17 GW=200.11.1.3 */
ping -c 1 200.11.1.17
/* This generates a re-direct which changes the route entry to
Dest=200.11.1.17 GW=200.11.1.17. This seems quite wrong....
the entry should be either deleted or resolved */
route delete 200.11.1.17
/* This causes a panic in the function rtfree(). If you dont delete the route
then the host address is unreachable (you get an arpresolve error).
*/
