Switch(config)# interface atm 0/0/3

Switch(config-if)# ip address 1.3.11.3 255.255.0.0

Switch(config-if)# tag-switching ip

Switch(config-if)# exit

To display the ATM interface configuration, use the following EXEC command:

The following example shows that tag switching is configured on ATM interfaces 0/0/3 and 1/0/1:

Switch# show tag-switching interfaces

Interface              IP    Tunnel   Operational

ATM0/0/3               Yes   No       Yes         (ATM tagging)

ATM1/0/1               Yes   No       Yes         (ATM tagging)

Enable OSPF on the ATM switch router so that it can create routing tables, which identify routes through 
the network. Then add the addresses and associated routing areas to the OSPF process so that it can 
propagate the addresses to other ATM switch routers:

Since the 12.0(1a)W5(5b) release of the system software, addressing the interface on the route processor 
(CPU) has changed. The ATM interface is now called atm0, and the Ethernet interface is now called 
ethernet0. Old formats (atm 2/0/0 and ethernet 2/0/0) are still supported.

The following is an example of OSPF enabled and assigned process number 10000. All addresses are in 
area 0:

Displays the tag switching configuration on 
the ATM interface.

Switch(config)# router ospf process_number

Switch(config-router)# 

Enables OSPF and assigns it a process number. 
The process number can be any positive integer.

Switch(config-router)# network address 
wildcard-mask area area-id

Defines the network prefix, a wildcard subnet 
mask, and the associated area number on which to 
run OSPF. An area number is an identification 
number for an OSPF address range.

Repeat this command for each additional area 
you want to add to the OSPF process.

Ethernet0 is used for system 

management only. Do not add this interface to the 
routing protocol process.
