Configuring IPX Multilayer Switching

IPX MLS Configuration Task List

Adding an IPX MLS Interface to a VTP Domain

Caution Perform this configuration task only if the switch connected to your router interfaces is in a VTP domain.

Perform the task before you enter any other IPX MLS interface command—specifically the mls rp ipx

or mls rp management-interface command. If you enter these commands before adding the interface

to a VTP domain, the interface will be automatically placed in a null domain. To place the IPX MLS

interface into a domain other than the null domain, clear the IPX MLS interface configuration before you

add the interface to another VTP domain. Refer to the section “Configuration, Verification, and

Troubleshooting Tips” and the Catalyst 5000 Software Configuration Guide, Release 5.1.

Determine which router interfaces you will use as IPX MLS interfaces and add them to the same VTP

domain as the switches.

To view the VTP configuration and its domain name on the switch, enter the show mls rp vtp-domain

EXEC command at the switch Console> prompt.

To assign an MLS interface to a specific VTP domain on the MLS-RP, use the following command in

interface configuration mode:

Enabling Multilayer Switching Protocol (MLSP) on the Router

To enable MLSP on the router, use the following command in global configuration mode:

Assigning a VLAN ID to a Router Interface

Note This task is not required for RSM VLAN interfaces (virtual interfaces), ISL-encapsulated interfaces, or

IEEE 802.1Q-encapsulated interfaces.

To assign a VLAN ID to an IPX MLS interface, use the following command in interface configuration

mode:

Command Purpose

Router(config-if)# mls rp vtp-domain domain-name

Adds an IPX MLS interface to a VTP domain.

Command Purpose

Router(config)# mls rp ipx

Globally enables MLSP on the router. MLSP is the

protocol that runs between the MLS-SE and

MLS-RP.

Command Purpose

Router(config-if)# mls rp vlan-id vlan-id-number

Assigns a VLAN ID to an IPX MLS interface.

The assigned IPX MLS interface must be either an

Ethernet or Fast Ethernet interface with no

subinterfaces.
