Introduction

This document provides MVRP configuration examples.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of MVRP.

Example: Configuring MVRP

Network configuration

As shown in Figure 1:

·     Device A and Device B are core layer devices. Device C and Device D are aggregation layer devices.

·     Ports on all devices allow packets from VLANs 11 through 30 to pass through.

·     MSTP implements load balancing and link backup for traffic of VLANs 11 through 30 between the core layer devices and the aggregation layer devices.

Configure MVRP on all devices to synchronize and update VLAN information. When the network is stable, set the registration mode to fixed on Ten-GigabitEthernet 1/0/1 of Device B to maintain dynamic VLAN information.

Figure 1 Network diagram

 

Analysis

To meet the network requirements, you must perform the following tasks:

·     To assign all devices to the same MST region, configure the same settings for the following parameters on all the devices:

¡     Spanning tree mode. (This example uses the default mode MSTP.)

¡     MST region name. (This example uses the region name test.)

¡     MST region revision level. (This example uses the default setting 0.)

¡     VLAN-to-instance mappings. (This example maps VLANs 11 through 20 to MSTI 1, and maps VLANs 21 through 30 to MSTI 2.)

·     For MSTIs 1 and 2 to use different uplinks for backup, set Device A and Device B as the root bridges of MSTIs 1 and 2, respectively.

·     Make sure each MSTI is mapped to an existing VLAN on each device in the network.

·     MVRP takes effect only on trunk ports. You must set the port link type to trunk for MVRP participants.

Applicable hardware and software versions

The following matrix shows the hardware and software versions to which this configuration example is applicable:

 

Hardware	Software version
S6520X-HI switch series S6520X-EI switch series	Supported in Release 1110P01
S6520X-SI switch series S6520-SI switch series S5000-EI switch series MS4600 switch series	Supported in Release 1110P01

 

Restrictions and guidelines

When you configure MVRP, follow these restrictions and guidelines:

·     MVRP can work with STP, RSTP, or MSTP. Ports blocked by STP, RSTP, or MSTP can receive and send MVRP frames. MVRP cannot work with other link layer topology protocols, including service loopback, PVST, RRPP, and Smart Link.

·     On a Layer 2 aggregate interface, MVRP takes effect on both the aggregate interface and all Selected member ports in the link aggregation group.

·     MVRP configuration made on an aggregation group member port takes effect only after the port is removed from the aggregation group.

Verifying VLAN information after changing the registration mode

When the network is stable, set the MVRP registration mode to fixed on Ten-GigabitEthernet 1/0/1 of Device B. Then, verify that dynamic VLANs on the port will not be deregistered.

# Set the MVRP registration mode to fixed on Ten-GigabitEthernet 1/0/1 of Device B.
