Configuring ATM Routing and PNNI
IISP Configuration
ATM Addresses
The autoconfigured ATM address of the ATM switch router suffices when implementing single-level
PNNI. Hierarchical PNNI requires an addressing scheme to ensure global uniqueness of the ATM
address and to plan for future network expansion.

IISP Configuration
This section describes the procedures necessary for Interim Interswitch Signaling Protocol (IISP)
configuration, and includes the following subsections:

Configuring the Routing Mode
The ATM routing software can be restricted to operate in static mode. In this mode, the call routing is
restricted to only the static configuration of ATM routes, disabling operation of any dynamic ATM
routing protocols, such as PNNI.

The atm routing-mode command is different from deleting all PNNI nodes using the node command
and affects Integrated Local Management Interface (ILMI) autoconfiguration. If the switch is configured
using static routing mode on each interface, the switch ILMI variable atmfAtmLayerNniSigVersion is
set to IISP. This causes either of the following to happen:

Note
The atm routing-mode command is activated only after the next software reload. The switch continues
to operate in the current mode until the software is reloaded.
