                        In this case, as ILMI has been disabled on the interface by issuing the no atm ilmi−enable command, the prefix is not sent to the router and hence, no address registration can occur. Access List Configuration Problems or ILMI Community Configured as Read−Only Access List configuration problems can occur if one of the workarounds proposed in this security notice is wrongly applied to the LightStream 1010 or the router. If you have added these lines to the switch configuration, ILMI (and PNNI) sto

Try issuing a shut/no shut command on the interface. If that does not help, contact Cisco Technical Support for further troubleshooting.

                        If you look at Tintin, you can see that Tintin is already using that NSAP address and has registered it on Casimir: Tintin# show lane client LE Client ATM1/0.1  ELAN name: ilmi−test  Admin: up  State: operational Client ID: 2                 LEC up for 39 seconds  Join Attempt: 4               HW Address: 0000.0000.0001   Type: ethernet             Max Frame Size: 1516 ATM Address: 47.00918100000000603E5A4501.000000000001.01  VCD  rxFrames  txFrames  Type       ATM Address    0         0

                        The router does not receive its prefix and hence no address−registration can occur. When enabling debug atm ilmi atm 0/0/0 on the LightStream 1010, this can be seen when the atm 0/0/0 interface is brought up: !−−− Output suppressed.
