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.
