Tops10/Tops20 has something caled "NETPTH" but it don't work like trace
route
that depends on packet TTL expire and ICMP replies, it actually talks management to each
node
and splices the path together.
[Routing path from MRC (59.41) to LEGATO (2.1)]
From Via Back Thru Cost Hops
MRC (59.41) =>NI-0-0 / TAP-0 <= OPS1VA (59.59) -1 -1

Subject: RE: [HECnet] Is MIM running?
It would be awesome to implement a
"traceroute" equivalent on something :-)
I assume we'd have to allow node inspection from remote, but I'm sure people
would be open for that.
I used to run a Cisco router for my area, but replaced it with pyDECnet as I
wanted to mix both GRE and point-to-point tunnels.
pyDECnet ticked all the boxes and was simple to implement.
The one thing that I miss, however, is the simplicity of "ping decnet" in
Cisco
IOS. Right from the router I could see if something was up or down.
Now I have to jump onto one of my boxes and do an ncp loop node to confirm the
same.
Would be nice to have the same implemented in pyDECnet, perhaps as a command
line option, or via the web gui.
If nobody else has any equipment handy, I could setup a router again at home and
do some captures.
Cheers, Wiz!!
