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.

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
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.
