Switch Administration

ATM Routing  

Enter the 

 command to create a static route to the IISP device:

SmartCell ZX # add atmroute

PortNumber(A1) : b2

AtmAddress() : 52:00:00:00:00:00:00:00:00:00:14:51:80

PrefixLength(104) :

Index(0) :

Type(Internal) :exterior

Scope(0) :

MetricsTag(0) :

SmartCell ZX #

The 

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

the route. For more on metrics and metric tags, see Section 4.2.3 “Route Metrics.”

Enter the 

 command to determine whether the route was created:

SmartCell ZX # show atmroute

AddressNumber(ALL)                        :

No. Port Route Address                                            Type Protocol

SmartCell ZX #

The route to the IISP device appears on the last line (Route No. 7).

Create a route on the IISP device that refers to the net prefix 
(

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

) of port 

 on the SmartCell 6A000.

For IISP routes to work with certain devices, ILMI may also need to be disabled 
on the SmartCell 6A000. Use the 

 command to disable ILMI on 

the SmartCell 6A000 on a per-port basis.

IISP Routing Considerations

When creating routes between the SmartCell 6A000 (running PNNI) and IISP devices, the criteria that characterize 
IISP connectivity still apply. To reach a SmartCell 6A000 within the PNNI domain, the IISP device must have a 
configured route that points directly to a port on the target SmartCell 6A000. Conversely, there must be a SmartCell 
6A000 that has a direct physical link (and a route over that link) to the IISP device. The following two examples 
illustrate this point.

In Figure 4-1 Switch A is an IISP device connected to the PNNI domain through Switch B. Switch A contains an LEC, 
which is a member of an ELAN whose LECS is on Switch C (within the PNNI domain). If the LEC on Switch A is to 
make contact with the LECS on Switch C, Switch A must contain an IISP route (denoted by the dotted line) directly 
to switch C. Furthermore, Switch B must contain a route to switch A over the physical link that connects the two 
switches.
