4ROUTING
4.1 ADDITIONAL ROUTING PROTOCOLS
Along with PNNI, all ATM SmartSwitches support additional ATM routing protocols:
• IISP — Use to connect with devices that do not support PNNI
• UNI — Use to connect end stations (also to connect devices whose implementation of ILMI is
incompatible with the ATM SmartSwitch)
Note Both IISP and UNI routes are created and modified using the ATMRoute command.
The proper route type is determined by the ATM SmartSwitch through interface
signaling information.
4.2 IISP ROUTES
Use the add atmroute command to create an IISP route that links the ATM SmartSwitch to a device that supports only
IISP routing. For example,
1. Physically connect port 5b2 of the SmartSwitch 6500 to the IISP device.
2. Enter show netprefix to determine the netprefix of port 5b2 on the SmartSwitch 6500:
SmartSwitch # show netprefix 5b2
Port NetPrefix
==============================================================================
5B2 39:00:00:00:00:00:00:00:00:00:14:41:80
SmartSwitch #
3. Determine the address of the IISP device. (For this example, this could be a port address, we use
52:00:00:00:00:00:00:00:00:00:14:51:80)
4. Enter the add atmroute command to create a static route to the IISP device:
SmartSwitch # add atmroute
PortNumber() : 5b2
AtmAddress() : 52:00:00:00:00:00:00:00:00:00:14:51:80
