Configuring MVRP

Overview

Multiple Registration Protocol (MRP) is an attribute registration protocol and transmits attribute
messages. Multiple VLAN Registration Protocol (MVRP) is a typical MRP application. MVRP
propagates and learns VLAN configuration among devices. MVRP enables a device to propagate
the local VLAN configuration to the other devices, receive VLAN configuration from other devices,
and dynamically update the local VLAN configuration (including the active VLANs and the ports
through which a VLAN can be reached). MVRP makes sure that all MVRP-enabled devices in a LAN
maintain the same VLAN configuration, and reduces the VLAN configuration workload. When the
network topology changes, MVRP can propagate and learn VLAN configuration information again
according to the new topology, and real-time synchronize the network topology.
MRP is an enhanced version of Generic Attribute Registration Protocol (GARP) and improves the
declaration efficiency. MVRP is an enhanced version of GARP VLAN Registration Protocol (GVRP).
MVRP delivers the following benefits over GVRP:
•
GVRP does not support the multiple spanning tree instance (MSTI). MVRP runs on a per-MSTI
basis, and implements per-VLAN redundant link calculation and load sharing.
•
MVRP decreases the number of packets transmitted for the same amount of VLAN
configuration, and improves the declaration efficiency.
For more information about GVRP, see "Configuring GVRP." For more information about MSTI, see
"Configuring spanning tree protocols."

Introduction to MRP

MRP allows participants in the same LAN to declare, propagate, and register information (for
example, VLAN information) on a per Multiple Spanning Tree Instance (MSTI) basis.
MRP implementation
Each port that participates in an MRP application (for example, MVRP) is called an "MRP participant".
Similarly, a port that participates in an MVRP application is called an "MVRP participant."
As shown in
MRP participants by sending declarations and withdrawals, and registers and deregisters the
attribute values of other participants according to the received declarations and withdrawals. MRP
rapidly propagates the configuration information of an MRP participant throughout the LAN.
Figure 68 MRP implementation
MVRP registers and deregisters VLAN attributes as follows:
•
When a port receives the declaration of a VLAN attribute, the port registers the VLAN and joins
the VLAN.
