Configuration Notes and Constraints
When configuring MVRP, pay attention to the following notes:
- GVRP and MVRP are mutually exclusive and can not be configured at the same time.
- The MVRP function can only work on Trunk type interfaces.
- MVRP is not allowed to be enabled on the host-side interfaces of the access devices at both ends of the network. However, users have to enable MVRP on all uplink interfaces of the access devices and all interfaces of intermediate devices.
- MVRP function conflicts with VLAN member function. That is, the static configuration of VLAN member is not allowed on the interface that enables MVRP function.
- On a single device, MVRP supports allocating up to 256 VLANs.
- STP/RSTP/MSTP blocking interface does not block MVRP PDUs.
- MVRP and Rapid PVST+ cannot be configured at the same time.
- It is not supported to deploy MVRP in MLAG topology.
- In the topology with loops, even if spanning tree is enabled, dynamic VLANs may not be removed by MVRP Leave/LeaveAll process.
- MVRP cannot be enabled on the routed interface or a member port of a LAG port.
- It is highly recommended to KEEP the default configurations of MVRP Timers to ensure the system and network stability. Modifying timers to inappropriate values might cause an imbalance in the operation of MVRP.
Configuring MVRP
Step1 Enable MVRP function globally.
set protocols mvrp enable <true | false>
Step2 Configure the port mode to trunk.
set interface gigabit-ethernet <interface-name> family ethernet-switching port-mode <port-mode>
Step3 Enable MVRP function on a specific interface.
NOTE:
To enable MVRP function, users need to enable MVRP function BOTH globally and at the per-interface level.
set protocols mvrp interface <interface-name> enable <true | false>
Step4 (Optional) Enable MVRP edge-switch function on the edge switch to prevent loops.
NOTE:
This command can be enabled only on the edge switches.
set protocols mvrp edge-switch <true | false>
Step5 (Optional) Configure MVRP timers.
set protocols mvrp join-timer <join-timer>
set protocols mvrp leave-timer <leave-timer>
set protocols mvrp leaveall-timer<leaveall-timer>
Step6 Commit the configuration.
