Hi Loi,
Have you configured using "atm nsap-address" or "atm esi-address". Today
while working on my ATM lab I came across a weird problem -
1) While working with "atm nsap-address" I was able to ping the remote
router. (0/16 and 0/5 were configured on both ends)
2) While working with "atm esi-address" I was unable to ping the remote
router (0/16 and 0/5 were configured). Weird enough I was learning the
ATM prefix from the ATM switch but end-to-end communication wasn't
happening.
Upon troubleshooting (debug atm ilmi) and (show atm ilmi-status) I
realized that the switch wasn't accepting the ESI registration.
Regards,
Pankaj K

Hi,
I have the same problem of can't ping to the adjacent router with the
similar configuration for svc.
Is it that difficult to just do a ping across svc?

Hi Ralph,
Not really sure about that. I don't think users can configure NSAP
addresses of their choice, they would be allocated by the service
providers. The choice is either to learn it statically or learn it using
ILMI.
I've got my ATM lab scheduled for tomorrow, will check it out. Chances
are someone else might clarify it for us by then.
Regards,
Pankaj K

You still need PVC 0/16 ILMI to register your NSAP address with the ATM
cloud via your local ATM switch. NSAP addresses are globally
significant, if you do not register your nsap address how will the atm
switches know to route your cells within the cloud. Unless you configure
a static route from the switch to the router.
Take a closer look at the ATM switch configuration. You can also check
if the atm switch is learning your nsap address, or your nsap address is
registered to a different node.

Hi Bob,
Since you are using static NSAP address configuration you don't need pvc
0/16. It is required only incase you are using learning the NSAP prefix
from the ATM switch.
You could use PVC 0/16 ilmi to learn the NSAP prefix and crosscheck with
those provided to you. "show atm ilmi-status"
Sample output
Router# show atm ilmi-status
Interface :ATM2/0 Interface Type :Unknown
ILMI VCC :(0, 16) ILMI Keepalive :Disabled
ILMI State: Restarting
Interface :ATM5/0 Interface Type :Private UNI (User-side)
ILMI VCC :(0, 16) ILMI Keepalive :Disabled
ILMI State: UpAndNormal
Peer IP Addr: 10.0.52.17 Peer IF Name: ATM1/1/0
Peer MaxVPIbits: 8 Peer MaxVCIbits: 14
Active Prefix(s) :
47.0091.8100.0000.0040.0b0a.2501
End-System Registered Address(s) :
47.0091.8100.0000.0040.0b0a.2501.bbbb.ccdd.eeff.12(Confirmed)
Moreover, to ping self IP address traffic must travel to the remote end
and return. Hence, map it to the remote NSAP address.

Pankaj K

Subject: ATM SVC configuration
Hello:
I am have an issue configuring SVC connections between my routers and
the ATM switch. (IPExpert LAB) I have tried several different
versions, with this one right out of the answer section for this
particular lab. I cannot, with any configuration, get a ping across the
link. I do not know if there is something else needed on the LS1010, as
those configurations are not
provided with the setup or solutions for the labs. Can someone please
point me in the right direction?
Have also tried with the arp-server self on one side and the arp-server
command with the nsap pointing to the other. No luck
