MVRP Configuration Notes
- MVRP is not supported with MSTP. MVRP is only supported with single IEEE 802.1w, PVST, and Per-VLAN RSTP.
- All dynamic VLANs created by the MVRP run STP by default.
- The default VLAN cannot be changed if the system is MVRP-enabled. Therefore, it is recommended that you change the default VLAN (optional) prior to enabling MVRP.
- The default VLAN is always in FIXED registration. Therefore, it is recommended to retain the MVRP ports in the system default VLAN and maintain the default VLAN consistency in the network.
- MVRP is not allowed on a Management port.
- VLANs that are learned dynamically cannot be deleted manually. Static VLANs cannot be deleted manually if they have dynamic ports learned by MVRP.
- Ports that are added dynamically cannot be removed manually from a dynamic or static VLAN.
- Static VLANs cannot be configured as forbidden VLANs.
- Dynamic VLAN creation by MVRP is enabled by
default. If you choose to change the default behavior using the
mvrp vlan-creation-disablecommand, it is recommended that you do so prior to enabling MVRP. - Dynamic VLANs created by MVRP can be converted to static VLANs using standard VLAN commands. Similarly, MVRP-added ports can be converted to static members by retagging the ports using VLAN port-tagging commands.
- VLANs created by MVRP do not support virtual routing interfaces. However, virtual routing interfaces are supported on statically configured VLANs even if MVRP adds ports to those VLANs.
- An MVRP periodic timer is not supported.
- Dynamic VLANs are not saved to the startup configuration and therefore will not persist across a reload. However, once the system is up, the protocol will relearn the dynamic VLANs.
- MVRP is supported on physical ports and LAG ports. However, an MVRP-enabled port cannot be added as a secondary port of a LAG.
- VLAN groups cannot be configured when MVRP is enabled.
- Maximum of 128 dynamic VLANs having Per-VLAN RSTP instances are supported.
