RE: ATM RFC 2684 svc don't work using full nsap address posted 10/17/2002

Not agree with Brian.

NSAP addr. can be assigned manually at every edge device OR automatically
(using ILMI)
Manually assigned NSAP addresses DO NOT require the use of ILMI (x/16).
If we use "esi-address" - we have to configure ILMI pvc (in this case switch
delivers NSAP address prefix via ILMI).
atm esi-address & atm nsap-address are mutually exclusive.
Any SVC requires QSAAL Pvc (x/5) - This is mandatory.

For example this config will work:

interface ATM0
 ip address 192.168.1.13 255.255.255.0
 pvc 0/5 qsaal
 !
 svc nsap 10.000000000000000000000000.888888888888.00
  protocol ip 192.168.1.14 broadcast
 !
 atm nsap-address 10.000000000000000000000000.999999999999.00
 no atm ilmi-keepalive
end
===========================================================
interface ATM0
 ip address 192.168.1.14 255.255.255.0
 pvc 0/5 qsaal
 !
 svc nsap 10.000000000000000000000000.999999999999.00
  protocol ip 192.168.1.13 broadcast
 !
 atm nsap-address 10.000000000000000000000000.888888888888.00
 no atm ilmi-keepalive
end
