Overview of MVRP

To manually create or delete VLANs for all the devices in a large and complex network, the workload will be very heavy, and it is very easy to make a configuration mistakenly for network administrator. In this case, users can complete the VLAN configuration through MVRP dynamic VLAN creation function.

Multiple VLAN Registration Protocol (MVRP) is an application of Multiple Registration Protocol (MRP) that is used to propagate and register VLAN configuration information on interfaces among devices. After the device enables MVRP, it sends the local VLAN configuration information to other devices, and also receives VLAN configuration information from other devices, so as to dynamically updates local VLAN configuration information to keep consistent with other devices in the network, which greatly reduces the VLAN configuration work for network administrator.

When the network topology changes, MVRP re-propagates and registers VLAN configuration information according to the new topology, so as to make VLAN configuration information on all the MVRP devices be updated synchronously with the network topology.

MVRP Timer

The supported MVRP timers are shown in the following table. Currently, changing the value of the timer is not supported.

MVRP edge-switch

For the MVRP access switch connected the host, when this switch forms a loop with other devices, it causes the MVRP messages received by this device to be forwarded cyclically over the same set of links, which consumes bandwidth and causes overutilization. To solve this problem, users can configure the following command to enable MVRP edge-switch function on the host-side switch, then the edge switch will not forward the received MVRP messages.
