Cabletron Systems ZX-250 manual Iisp Routing Considerations, AtmAddress

Switch Administration ATMRouting

T• Enter the add ATMRoute 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 #

2p›F 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.”

Q• Enter the show ATMRoute command to determine whether the route was created:

SmartCell ZX # show atmroute
AddressNumber(ALL)	:
No. Port Route Address	Type Protocol

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 b2 on the SmartCell ZX-250.

2p›F For IISP routes to work with certain devices, ILMI may also need to be disabled on the SmartCell ZX-250. Use the set PortConfig command to disable ILMI on the SmartCell ZX-250 on a per-port basis.

IISP Routing Considerations

When creating routes between the SmartCell ZX-250 (running PNNI) and IISP devices, the criteria that characterize IISP connectivity still apply. To reach a SmartCell ZX-250 within the PNNI domain, the IISP device must have a configured route that points directly to a port on the target SmartCell ZX-250. Conversely, there must be a SmartCell ZX-250 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 4-1Switch 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.
