Switch Administration

ATMRouting

4.Enter the add ATMRoute command to create a static route to the IISP device:

SmartSwitch # 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) :

SmartSwitch #

Note The add ATMRoute 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.”

5.Enter the show ATMRoute command to determine whether the route was created:

SmartSwitch # show

SmartSwitch #

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

6.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 b2 on the SmartSwitch 9A100.

Note For IISP routes to work with certain devices, ILMI may also need to be disabled on the SmartSwitch 9A100. Use the set PortConfig command to disable ILMI on the SmartSwitch 9A100 on a per-port basis.

IISP Routing Considerations

When creating routes between the SmartSwitch 9A100 (running PNNI) and IISP devices, the criteria that characterize IISP connectivity still apply. To reach a SmartSwitch 9A100 within the PNNI domain, the IISP device must have a configured route that points directly to a port on the target SmartSwitch 9A100. Conversely, there must be a SmartCell 9A100 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.
