The exact same issue was presented in the ECP1 class with Val Pavlichenko
this week. In addition to not knowing the vpi/vci values, he added the
additional caveat that you dont know any information except the remote
endpoint is a BGP speaker, that it is correctly configured to speak to you,
and that it is somewhere in the 192.0.0.0/8 Ip address range.
Determine your VPI/VCI pair & your IP Address.

I can envision two cases where this might be helpful. One is where the exam
instructs you that a PVC exists between r1 and r3. You go to the proctor and
say "but I don't know what the VPI/VCI values are" and the proctor says
"that's right." In this case I think I would take my approach and ask the
proctor if it was ok if I manually moved it to my subinterface.
The other case would be where the lab asked you to somehow dynamically use
and discover them. In this case you can use atm ilmi-pvc-discovery
subinterface. In this case the router assigns PVCs to the subinterface with
the same number as the VPI of the PVC. So any PVC with a VPI=1 goes to
subinterface 0.1, etc. I've never actually tried this one...

That is a very good suggestion.. My only concern is if the test ask you to
use auto-discovery, you might get marked off... Comments?

We did this in the ECP1 class last week. The suggestion is to enable atm
ilmi-pvc-discovery on your atm main interface. Then do a "show atm pvc" (or
show atm vc). This will then show you the VPI/VCI of any PVC's the router
discovered via ilmi with the switch. Then once you know the PVCs (and their
VPI/VCI), actually go to the atm interface (or subinterface) and manually
define them with the atm pvc vcd vpi vci (or pvc vpi/vci) command. Then you
can do your normal mappings, inarp, etc.
Its a nice tool in the event you are given a PVC, but not told what the
VPI/VCI values are.
Rob.

anyone on the list who have access to ATM gear - Can u guys confirm this
pattern or suggest any ideas here to fix ?
Cheers,Padhu

I tried this a few weeks ago and couldn't get this to work with eigrp
...debug ip pack shows encaps failed ...although it assigned the pvcs to the
"correct numbered " subinterface that i had created. It was rental so didnt
have too muh time to figure it

Did anyonve have any problems with ilmi-pvc-discovery command and running
routing protocolss over the atm pvc? If I manually configure the atm pvc's
mappings into the router eigrp works great, but if I use ilmi auto
discovery, I was never able to form adjancey over EIGRP...Thoughts?
Thank you,
Robert
