Configuring MVRP


MVRP must be enabled globally to facilitate dynamic VLAN learning.


  1. Enable MVRP globally on all interfaces or only for specific interfaces with the command mvrp. (For Dynamic LAGs, MVRP is enabled by default).
  2. By default, MVRP supports dynamic registration and deregistration of VLANs on all interfaces. If required, customize the behavior for each interface with the command mvrp registration.
  3. If required, adjust the MVRP timers from their default values with the command mvrp timer. To avoid frequent registrations and deregistrations, use the same MVRP timer values throughout the network.
  4. Review your MVRP configuration settings with the commands show mvrp config, show mvrp state, and show mvrp statistics.


This example creates the following configuration:

  • Enables MVRP on all interfaces.
  • Sets interface 1/1/1 to ignore VLAN 100.
