IISP Routing

IISP routing connects two or more switches (or other devices). Through SVCs, IISP routes create user-transparent links 
over which IP over ATM and LANE members can operate with each other and their respective support servers (ARP 
server, LECS, LES, and so on). For example, if a VLAN spans two or more switches, all nodes in the VLAN can 
communicate with the ARP server and with each other if the switches are connected using IISP routes.

Creating IISP Routes

Use the 

 command to create IISP routes. IISP routes are defined on each switch by the port number 

through which the route exists and the netprefix of the switch at the opposite end.

For example, to set up an IISP route between port A4 on switch SW1 and port A4 of SW2, you would perform the 
following steps.

Physically connect port A4 of switch SW1 to port A4 of switch SW2.

If the netprefixes of port A4 on SW1 and port A4 on SW2 are not already known, enter the 

 command on each switch.

For switch SW1, enter:

SmartCell ZX # show netprefix a4

 Port#   NetPrefix

============================================================================

A4 39:00:00:00:00:00:00:00:00:00:14:41:80 

<SW1's netprefix for port A4

SmartCell ZX #

For switch SW2, enter

SmartCell ZX # show netprefix a4

 Port#   NetPrefix

============================================================================

A4 39:00:00:00:00:00:00:00:00:00:14:47:80 

<SW2's netprefix for port A4

SmartCell ZX # 

Enter the 

command on each switch.

From SW1, enter

SmartCell ZX # add iisproute

ATMAdress() : 39:00:00:00:00:00:00:00:00:00:14:47:80
