4.3.1 IISP Routin
g
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.

IISP Routes
Use the add iisproute 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.
1. Physically connect port A4 of switch SW1 to port A4 of switch SW2.
2. If the netprefixes of port A4 on SW1 and port A4 on SW2 are not already known, enter the show
netprefix
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

3. Enter the add iisproute 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
<SW2's netprefix
PortNumber(A1) :a4
<Specify A4 as the port

From SW2, enter
SmartCell ZX # add iisproute
ATMAdress() : 39:00:00:00:00:00:00:00:00:00:14:41:80
PortNumber(A1) : A4
<Specify A4 as the port

4. To see if the IISP routes exist, use the show iisproute command on each switch.
From SW1, enter
SmartCell ZX # show iisproute
