The multi-ring network supported by HVRP has the following characteristics:
l MSTP is enabled on the entire network. Each ring maps an MSTP instance, and all the
devices on the ring belong to the same region.
l SwitchA is the root bridge and other Switches connect to the Layer 3 device (the ME60)
through SwitchA.
12.3 Enabling HVRP
This section describes how to enable HVRP.
12.3.1 Establishing the Configuration Task
Applicable Environment
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 12-4, 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.
