[nsp] possible ip route bug

[ROY]

Has anyone had an experience where a static route "ip route x.x.x.x
x.x.x.x SeY/Z" cannot be deleted from the configuration, which "show
running-config" displays? The route is not being recognized by the
equipment, but, adding another similar entry will make the route appear
on the routing table. 

Deleting the entry removes the route from the routing table, and only
one of the config lines.

Trying to delete the original line yeilds "%No matching route to delete"

I'm running 

IOS (tm) 7200 Software (C7200-JO3S-M), Version 12.2(17a), RELEASE
SOFTWARE (fc1)

on 

C7204VXR (NPE400)

has been up for 24 weeks.

Any ideas?

TIA.
