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.

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
