Configuring MVRP
This chapter describes how to configure the IEEE 802.1ak Multiple VLAN Registration Protocol
(MVRP) on the Catalyst 6500 series switches.
Note For complete syntax and usage information for the commands that are used in this chapter, refer to the
Catalyst 6500 Series Switch Command Reference publication.
This chapter consists of these sections:
• Understanding How MVRP Works, page 18-1
• Default MVRP Configuration, page 18-2
• MVRP Configuration Guidelines, page 18-2
• Configuring MVRP on the Switch, page 18-3
Note MVRP requires Catalyst 6500 series switch software release 8.7(1) or later.
Understanding How MVRP Works
MVRP is an MRP application that provides IEEE 802.1ak-compliant VLAN pruning and dynamic
VLAN creation on trunk ports.
With MVRP, the switch can exchange VLAN configuration information with other MVRP switches,
prune the unnecessary broadcast and unknown unicast traffic, and dynamically create and manage the
VLANs on the switches that are connected through trunk ports.
Note MRP and MVRP are industry-standard protocols that are described in IEEE 802.1ak.
Note MVRP replaces GVRP with faster and smaller transmissions, and extends support to larger networks and
4k (4094) VLANs.
