12.5 Configuration Examples
This section provides a configuration example of HVRP.
12.5.1 Example for Configuring HVRP
Networking Requirements
A switch on a Layer 2 network needs to learn a large number of MAC addresses. To reduce the
MAC addresses that the switch needs to learn, you can enable HVRP on the switch. As shown
in Figure 12-5, HVRP needs to be configured on a single-ring network.
Through the dynamic VLAN registration and aging mechanism, HVRP ages the VLANs on the
interfaces that do not forward packets and saves only necessary VLANs. When a VLAN contains
two or less than two interfaces, the interfaces do not need to learn MAC addresses. Instead, the
interfaces broadcast data packets in the VLAN without affecting the bandwidth.
