Configuring MVRP

Multiple Registration Protocol (MRP) is an attribute registration protocol used to transmit attribute
values. Multiple VLAN Registration Protocol (MVRP) is a typical MRP application. It synchronizes
VLAN information among devices.
MVRP propagates local VLAN information to other devices, receives VLAN information from other
devices, and dynamically updates local VLAN information. When the network topology changes,
MVRP propagates and learns VLAN information again according to the new topology.

MRP

MRP allows devices in the same LAN to transmit attribute values on a per MSTI basis. For more
information about MSTIs, see "Configuring spanning tree protocols."

MRP implementation

An MRP-enabled port is called an MRP participant. An MVRP-enabled port is called an MVRP
participant.

participants to register and deregister its attribute values. It also 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 1 MRP implementation
For example, MRP registers and deregisters VLAN attributes as follows:
•
When a port receives a declaration for a VLAN, the port registers the VLAN and joins the VLAN.
•
When a port receives a withdrawal for a VLAN, the port deregisters the VLAN and leaves the
VLAN.
Figure 1 shows a simple MRP implementation on an MSTI. In a network with multiple MSTIs, MRP
performs attribute registration and deregistration on a per-MSTI basis.

MRP messages

MRP messages include the following types:
•
Declaration—Includes Join and New messages.
•
Withdrawal—Includes Leave and LeaveAll messages.
