on an X25 you can issue the 'show x25 route' command which can give you something like the following output:
r1#sh x25 route
# Match Substitute Route to match/use
0 dest ^4111(.*) Sub-dest \1 Serial1/0 1123/4
Now the question raised:
How can we reset the value for the output on match/use? Is it possible at all without rebbot of the router?
I haven't found any cmd which will do this up to now, also I was thinking about to 'clear' the routing table for X25, but also this seems not to be possible.
Any comment/help is welcome, thanks Thomas
