IISP Routes

  Routing

For IISP routes, always set the 

 parameter of the 

 command to 

. This indicates that the route is external to the PNNI domain.

The 

 command allows you to specify a set of metrics to be used with 

the route. Metrics are created using the 

 command, and are 

assigned to routes by metric tag numbers. By setting the appropriate 
administrative weights within metrics, it’s possible to create parallel load-sharing 
or fail-over routes. For more information about metrics, administrative weights, 
and metric tags, see Section 4.4, Route Metrics.

Enter the 

 command to determine whether the route was created:

SmartSwitch # show atmroute

AddressNumber(ALL)                        :

No. Port Route Address                                            Type Protocol

SmartSwitch #

The route to the IISP device appears as 

, and with Protocol Type of 

 (management).

Create a route on the IISP device that refers to the netprefix 
(

39:00:00:00:00:00:00:00:00:00:14:41:80

) of port 

 on the SmartSwitch 6500.

For IISP routes to work with certain devices, ILMI may need to be disabled on the 
ATM SmartSwitch. Use the 

 command to disable ILMI on the 

ATM SmartSwitch on a per-port basis.

IISP Routing Considerations

When creating routes between an ATM SmartSwitch (running PNNI) and IISP devices, the criteria that characterize 
IISP connectivity still apply. To reach an ATM SmartSwitch within the PNNI domain, the IISP device must have a 
configured route that points directly to a port on the target ATM SmartSwitch. Conversely, there must be an ATM 
SmartSwitch that has a direct physical link (and a route over that link) to the IISP device. The following two examples 
illustrate this point.
