Configuring Tag Switching on an ATM Switch Router

Configuring Tag Switching on an ATM Switch Router

This section describes how to configure tag switching on an ATM switch router, and includes the following procedures:

Enabling Tag Switching on the ATM Interface

Configuring the Routing Protocol

Enabling Tag Switching on the ATM Interface

Note Configure all parallel interfaces between switches for either IP unnumbered or with a specific IP address. Unnumbering some parallel interfaces and assigning specific IP addresses to others might cause Tag Distribution Protocol (TDP) sessions to restart on some parallel interfaces when another parallel interface is shut down. Therefore, we highly recommend that you unnumber all parallel interfaces to loopback.

Take these steps:

Step Command

1Switch(config)# interface atm card/subcard/port

Switch(config-if)#

2Switch(config-if)# ip unnumbered type number

or

Switch(config-if)# ip address ip-address mask

Purpose

Enter interface configuration mode on the specified ATM interface.

Enable IP unnumbered on the ATM interface and assign the unnumbered interface to an interface that has an IP address. We recommend enabling IP unnumbered because it allows you to conserve IP addresses and reduces the number of TVCs1 terminating on the switch.

or

Assign an IP address and subnet mask to the ATM interface.
