4 ROUTING

4.1ADDITIONAL 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.

4.2IISP 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
