• Effectively reduces the number of LeaveAll messages in the network.
• Prevents the LeaveAll timer of a particular participant from always expiring first.
MVRP registration modes
VLAN information propagated by MVRP includes dynamic VLAN information from other devices and
local static VLAN information.
MVRP has the following registration modes, which process dynamic VLANs in different ways.
Normal
An MVRP participant in normal registration mode registers and deregisters dynamic VLANs.
Fixed
An MVRP participant in fixed registration mode disables deregistering dynamic VLANs and drops
received MVRP frames. The MVRP participant does not deregister dynamic VLANs or register new
dynamic VLANs.
Forbidden
An MVRP participant in forbidden registration mode disables registering dynamic VLANs and drops
received MVRP frames. The MVRP participant does not register new dynamic VLANs or re-register
a deregistered dynamic VLAN.

Configuration restrictions and guidelines
When you configure MVRP, follow these restrictions and guidelines:
• MVRP can work with STP, RSTP, or MSTP. Ports blocked by STP, RSTP, or MSTP can receive
and send MVRP frames. Do not configure MVRP with other link layer topology protocols, such
as service loopback, PVST, RRPP, and Smart Link.
For more information about STP, RSTP, MSTP, and PVST, see "Configuring spanning tree
proto
cols." For more information about service loopback, see "Configuring service loopback
grou
ps." For more information about RRPP and Smart Link, see High Availability Configuration
Guide.
• Do not configure both MVRP and remote port mirroring on a port. Otherwise, MVRP might
register the remote probe VLAN with incorrect ports, which would cause the monitor port to
