Multiple Registration Protocol 1607

Multiple Registration Protocol

Dell EMC Networking N3000E-ON and N3100-ON Series Switches

Overview

Multiple Registration Protocol (MRP) is a suite of protocols for reserving

resources in the network to facilitate configuration of the network. MRP uses

the following protocols:

• Multiple VLAN Registration Protocol (MVRP) — Replaces the role of

GVRP in dynamic VLAN creation. MVRP propagates dynamic VLAN

information to participating bridges. The participating bridges register (or

withdraw) VLAN ID registrations for propagation of AVB streams. If a

VLAN ID is dynamically registered on a bridge port, the bridge forwards

frames for that VLAN ID on the port.

• Multiple MAC Registration Protocol — Replaces the role of GMRP in

dynamic (M)FDB entry creation. MMRP propagates the association of a

MAC address (associated with an AVB stream) to a VLAN. This helps to

determine to what part of a network a given MAC address needs to be

transmitted. If a MAC address is registered on a bridge port by MMRP, the

bridge forwards frames addressed to that MAC address on the port.

MMRP and MVRP share a common framework that provides services to the

individual protocols. The common framework is the Multiple Registration

Protocol (MRP). MRP allows participants in an MRP application to register

attributes with other participants in a Bridged LAN. Each MRP participant

maintains:

• Registrar and Applicant state machine for each attribute of interest

• LeaveAll and PeriodicTransmission state machine support for the

participant

NOTE: Support for MMRP/MVRP is available on the N3100-ON and N3000E-ON

models when utilizing the Advanced firmware.
