Yes, I was catching up on that, but perhaps not keeping up with it...
So what's the bottom line here? Is netpth rolling over and dying
actually legitimate or is there a better algorithm to use?

Paul have this fixed in his code now. Next version should have it fixed.

looking. The code is kind of odd in that it is half Tops-10 and half
Tops-20, but not in a GLXLIB sort of way.
That being said, what you've pointed out strikes me as correct. Now,
if I just look at the show node /xxx/status, I was wondering about
something:
NCP>*tell a2rtr:: shoW noDE twenex:: statUS *
Remote Node = 31.29 (TWENEX)
Circuit = DMC-31
Next Node = 31.3 (PYRTR)
NCP>*telL pyrtr:: shoW noDE twenex:: statUS *
Remote Node = 31.29 (TWENEX)
State = Reachable
Delay = 1
Cost = 24
Hops = 2
Circuit = MUL-31-32
Isn't pyrtr:: supposed to be telling me what the next node is?
Maybe that's why netpth is asking about circuits?

Obviously, there is no good reason to ask for the
circuit
information. You already got all you needed from the show node xx
status, right?

To unsubscribe send an email to hecnet-leave(a)lists.dfupdate.se It sits in a loop doing the following:
show node xxx:: status
From that it picks out the appropriate circuit and does a
show circuit xxx status
So, to show the path from venti2:: to twenex::, the first few
commands would be
