Configuring MLS with MSFC Hybrid Mode

As with the RSM and Catalyst 5000 Supervisor MLS configurations, the Layer 2 Catalyst Supervisor has MLS processing enabled by default (in fact, it currently cannot be disabled on a Catalyst 6000). Also similar to MLS on the 5000s, the MSFC RP is not configured to provide MLS service by default. To add MLS to an already functioning MSFC RP router configuration, complete the following four-step process:

Step 1.

Globally enable MLS on the RP with the mls rp ip command. (You can also use mls rp ipx for the IPX protocol.)

Step 2.

Configure a VLAN Trunking Protocol (VTP) domain for each VLAN interface using the mls rp vtp-domain domain_name command.

Step 3.

Enable MLS on each VLAN interface using the mls rp ip or mls rp ipx commands.

Step 4.

Select one or more router interfaces to send MLSP packets using the mls rp management-interface command.


Chapter 11 presented this list as a five-step list because it included a step (Step 3) to configure non-trunk links on external routers. Because this is not necessary for integrated routers such as the MSFC RP, this step has been omitted here.

For example, the configuration displayed in Example 18-6 enables MLS for VLANs 1 through 3 on an MSFC RP (both IP and IPX are configured)
