Multiple Registration Protocol (MRP) is an attribute registration protocol and transmits attribute messages. An application that complies with MRP is called an “MRP application”. Multiple VLAN Registration Protocol (MVRP) is a typical MRP application. 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) and improves the declaration efficiency. MVRP propagates VLAN configuration information among devices, and enables devices to learn and automatically synchronize VLAN configuration information, reducing the 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. For more information about GVRP, see the chapter “Configuring GVRP.”

Introduction to MRP

Different from GARP, 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”.

MRP rapidly propagates the configuration information of an MRP participant throughout the LAN. As shown in Figure 1, an MRP participant registers and deregisters its attribute values on other MRP participants by sending declarations and withdrawals, and registers and deregisters the attribute values of other participants according to the received declarations and withdrawals.

Figure 1 MRP implementation

MRP messages

MRP exchanges information among MRP participants by advertising MRP messages, including Join, New, Leave, and LeaveAll. Join and New messages are declarations, and Leave and LeaveAll messages are withdrawals. As an MRP application, MVRP also uses MRP messages for information exchange.

1. Join message

An MRP participant sends Join messages when it wishes to declare its attribute values and receives Join messages from other MRP participants. When receiving a Join message, an MRP participant sends a Join message to all participants except the sender.

Join messages fall into the following types:

? JoinEmpty—An MRP participant sends JoinEmpty messages to declare attribute values that it has not registered.

? JoinIn—An MRP participant sends JoinIn messages to declare attribute values that it has registered.

2. New message

When the Multiple Spanning Tree Protocol (MSTP) topology changes, in other words, when an MSTP TcDetected event occurs, an MRP participant sends New messages to declare the topology change. On receiving a New message, an MRP participant sends a New message out each port except the receiving port. Similar to a Join message, a New message enables MRP participants to register attributes.

3. Leave message

An MRP participant sends Leave messages when it wishes to withdraw declarations of its attribute values and receives Leave messages from other participants. When receiving a Leave message, an MRP participant sends a Leave message to all participants except the sender.

4. LeaveAll message

Each MRP participant is configured with an individual LeaveAll timer. When the timer expires, the MRP participant sends LeaveAll messages to deregister all attributes, so that any other MRP participant can re-register all attributes. This process periodically clears the useless attributes in the network. On receiving a LeaveAll message, MRP determines whether to send a Join message to request the sender to re-register these attributes according to attribute status. On sending a LeaveAll message, MRP restarts the LeaveAll timer.

MRP timers

The implementation of MRP uses the following timers to control MRP message transmission.

1. Periodic timer

On startup, an MRP participant starts its own Periodic timer to control MRP message transmission. The MRP participant collects the MRP messages to be sent before the Periodic timer expires, and sends the MRP messages in as few packets as possible when the Periodic timer expires and meanwhile restarts the Periodic timer. This mechanism reduces the number of MRP protocol packets periodically sent.

NOTE:

You can enable or disable the Periodic timer at the CLI. When you disable the Periodic timer, MRP will not send MRP messages.

2. Join timer

The Join timer control the transmission of Join messages. To make sure that Join messages can be reliably transmitted to other participants, an MRP participant waits for a period of the Join timer after sending a Join message. If the participant receives JoinIn messages from other participants before the Join timer expires, the participant does not re-send the Join message. When both the Join timer and the Periodic timer expire, the participant re-sends the Join message.

3. Leave timer

The Leave timer controls the deregistration of attributes. When an MRP participant wishes other participants to deregister its attributes, it sends a Leave message. On receiving a Leave message, MRP starts the Leave timer, and deregisters the attributes if it does not receive any Join message for the attributes before the Leave timer expires.

4. LeaveAll timer

On startup, an MRP participant starts its own LeaveAll timer. When the LeaveAll timer expires, MRP sends out a LeaveAll message and restarts the LeaveAll timer. On receiving the LeaveAll message, other participants re-register all the attributes and re-start their LeaveAll timer.

NOTE:

Though MRP participants throughout the network may be configured with different LeaveAll timers, an MRP participant sends LeaveAll messages at the smallest interval among the neighboring participants’ LeaveAll timers. At the next startup, the LeaveAll timer of each participant randomly changes within a certain range.

MRP protocol packet encapsulation format

Figure 2 MRP protocol packet encapsulation format

Figure 2 shows the format of an MRP protocol packet encapsulated in an IEEE 802.3 Ethernet frame.

Table 1 MRP protocol packet fields

Field	Description
MRPDU	MRP protocol data unit (MRPDU) encapsulated in the MRP protocol packet.
Protocol Version	Protocol version, which is 0.
Message	Attribute message, which comprises the Attribute Type, Attribute Length, and Attribute List fields.
End Mark	End mark of the MRPDU or an attribute list field. This field is fixed at 0x00.
Attribute Type	Attribute type, which is VID Vector specified by the value of 1.
Attribute Length	Length of the FirstValue field, which is 2 as specified by MVRP.
Attribute List	Attribute list, which comprises multiple attributes.
Vector Attribute	Vector attribute, which comprises the VectorHeader, FirstValue, and Vector fields.
Vector Header	Vector header, which comprises the LeaveAllEvent and NumberOfValues fields.
FirstValue	The first attribute value encapsulated in the MVRP protocol packet.
Vector	Attribute events, where each byte specifies three attribute events. The attribute events include: · 0x00—New operator · 0x01—JoinIn operator · 0x02—In operator · 0x03—JoinMt operator · 0x04—Mt operator · 0x05—Lv operator Assume that the three attribute events sharing a byte are A1, A2, and A3. The value of the byte A1A2A3 is ((A1 * 6 + A2) * 6) + A3, which ranges from 0 to 255.
LeaveAll Event	LeaveAll event indicator: · 0—Not a LeaveAll event · 1—A LeaveAll event
Number of Values	A 13-bit field, which shows the number of attribute values encoded in the Vector field.

The destination MAC addresses of MRP protocol packets are multicast MAC addresses, and vary with MRP applications. For example, the destination MAC address is 01-80-C2-00-00-21 and the EtherType is 88F5 for MVRP protocol packets. When a device receives a packet from an MRP participant, it delivers the packet to the MRP application identified by the destination MAC address.

MVRP implementation

MVRP overview

As an MRP application, MVRP uses the operating mechanism of MRP to maintain and propagate dynamic VLAN registration information throughout the network.

In a LAN, each MVRP-enabled device can receive the VLAN registration information from other MVRP devices, and dynamically update its local database, including active VLANs and the ports through which a VLAN can be reached. This makes sure that all MVRP-enabled devices in a LAN maintain the same VLAN information.

The VLAN information propagated by MVRP includes not only locally, manually configured static VLAN information but also dynamic VLAN information from other devices.

MVRP implementation mechanisms

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.

· When a port receives the withdrawal of a VLAN attribute, the port deregisters the VLAN and leaves the VLAN.

NOTE:

Figure 1 shows a simple MVRP implementation on an MSTI. In a network with multiple MSTIs, VLAN registration and deregistration are performed on a per-MSTI basis. For more information about MSTIs, see the chapter “Configuring the spanning tree.”

MVRP registration modes

VLANs created manually, locally are called “static VLANs”, and VLANs learned through MVRP are called “dynamic VLANs”. The following MVRP registration modes are available.

· Normal

A port in normal registration mode performs dynamic VLAN registrations and deregistrations, and sends declarations and withdrawals for dynamic and static VLANs.

· Fixed

A port in fixed registration mode disables deregistering dynamic VLANs, sends declarations for dynamic VLANs and static VLANs, and drops received MVRP protocol packets. As a result, a trunk port in fixed registration mode does not deregister or register dynamic VLANs.

· Forbidden

A port in forbidden registration mode disables registering dynamic VLANs, sends declarations for dynamic VLANs and static VLANs, and drops received MVRP protocol packets. As a result, a trunk port in forbidden registration mode does not register dynamic VLANs, and does not re-register a dynamic VLAN when the VLAN is deregistered.

MVRP configuration task list

To configure MVRP, perform the following tasks:

Task	Remarks
Configuring MVRP	Optional
Configuring MRP timers	Optional
Enabling GVRP compatibility	Optional

NOTE:

· MVRP configuration made in Ethernet interface view or Layer 2 aggregate interface view takes effect on the current interface only; MVRP configuration made in port group view takes effect on all the member ports in the group.

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

Configuring MVRP

Before enabling MVRP on a port, you must enable MVRP globally. You can configure MVRP only on trunk ports, and you must assign the involved trunk ports to all dynamic VLANs.

CAUTION:

· MVRP and service loopback are mutually exclusive.

· MVRP can work with STP, RSTP, or MSTP, but not other link layer topology protocols, including PVST, RRPP, and Smart Link. Ports blocked by STP, RSTP, or MSTP can receive and send MVRP protocol packets. For more information about STP, RSTP, MSTP, and PVST, see the chapter “Configuring the spanning tree.” For more information about RRPP and Smart Link, see High Availability Configuration Guide.

· Do not enable both MVRP and remote port mirroring on a port. Otherwise, MVRP may register the remote probe VLAN to unexpected ports, which would cause the monitor port to receive undesired duplicates. For more information about port mirroring, see Network Management and Monitoring Configuration Guide.

· Enabling MVRP on a Layer 2 aggregate interface enables both the aggregate interface and all Selected member ports in the link aggregation group to participate in dynamic VLAN registration and deregistration.

· MVRP runs on a per-MSTI basis. When configuring MVRP, make sure that all MSTIs in the network are effective and each MSTI is mapped to an existing VLAN on each device in the network.

To configure MVRP:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enable MVRP globally.	mvrp global enable	By default, MVRP is globally disabled.
3. Enter interface view.	· Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view: interface interface-type interface-number · Enter port group view: port-group manual port-group-name	Use one of the commands.
4. Configure the port as a trunk port.	port link-type trunk	By default, the link type of a port is access.
5. Configure the port to permit all VLANs.	port trunk permit vlan all	By default, a trunk port permits only VLAN 1.
6. Enable MVRP on the port.	mvrp enable	By default, MVRP is disabled on a port.
7. Set the MVRP registration mode.	mvrp registration { fixed \| forbidden \| normal }	Optional. The default setting is normal registration mode.

NOTE:

For more information about the port link-type trunk and port trunk permit vlan all commands, see Layer 2—LAN Switching Command Reference.

Configuring MRP timers

NOTE:

· The MRP timers apply to all MRP applications, for example, MVRP, on a port. To avoid frequent VLAN registrations and deregistrations, use the same MRP timers throughout the network.

· Each port maintains its own Periodic, Join, and LeaveAll timers, and each attribute of a port maintains a Leave timer.

To configure MRP timers:

To do…	Use the command…	Remarks
1. Enter system view	system-view	N/A
2. Enter interface view	· Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view: interface interface-type interface-number · Enter port group view: port-group manual port-group-name	Use one of the commands.
3. Configure the LeaveAll timer	mrp timer leaveall timer-value	Optional. The default setting is 1000 centiseconds.
4. Configure the Join timer	mrp timer join timer-value	Optional. The default setting is 20 centiseconds.
5. Configure the Leave timer	mrp timer leave timer-value	Optional. The default setting is 60 centiseconds.
6. Configure the Periodic timer	mrp timer periodic timer-value	Optional. The default setting is 100 centiseconds.

Table 2 shows the value ranges for MRP timers (including Join, Leave, and LeaveAll timers) and their dependencies.

· If you set a timer to a value beyond the allowed value range, your configuration will fail. To do that, you can change the allowed value range by tuning the value of another related timer.

· To restore the default settings of the timers, restore the Join timer first, followed by the Leave and LeaveAll timers. You can restore the Periodic timer to the default at any time.

Table 2 Dependencies of the MRP timers

Timer	Lower limit	Upper limit
Join	20 centiseconds	Half the Leave timer
Leave	Twice the Join timer	LeaveAll timer
LeaveAll	Leave timer on each port	32760 centiseconds

Enabling GVRP compatibility

NOTE:

· With GVRP compatibility enabled, MVRP can work with only STP or RSTP rather than MSTP. In this case, if MVRP and MSTP run at the same time, the network might fail to work properly.

· With GVRP compatibility enabled, H3C recommends that you disable the Periodic timer for MVRP. Otherwise, the VLAN status might change frequently when the system is busy.

MVRP can be compatible with GVRP. When the peer device supports GVRP, you can enable GVRP compatibility on the local end, so that the local end can receive and send MVRP and GVRP protocol packets at the same time.

To enable GVRP compatibility:

Step	Command	Remarks
1. Enter system view	system-view	N/A
2. Enable GVRP compatibility	mvrp gvrp-compliance enable	By default, GVRP compatibility is disabled.
