Basic Concepts

Basic Concepts

HVRP Concepts

  • HVRP interface

    An interface that is configured with HVRP attributes. It can send, receive, and process HVRP packets.

  • HVRP root interface

    An HVRP interface that functions as the root interface in a Spanning Tree Protocol (STP) region.

  • HVRP designated interface

    An HVRP interface that functions as the designated interface in an STP region.

  • Local VLAN/User VLAN

    A VLAN that does not contain any HVRP interface.

  • VLAN registration

    A process of adding HVRP interfaces to VLANs that meet certain conditions in tagged mode.

  • VLAN aging

    A process of deleting a VLAN from an HVRP interface.

  • Permanent VLAN

    A VLAN that is never aged by an HVRP interface.

  • Local VLAN information sending

    The HVRP root interface sends HVRP packets containing local VLAN information after STP and HVRP are enabled.

  • VLAN registration timer

    A timer that specifies the interval at which HVRP VLAN registration packets are sent.

  • Aging timer of registered VLANs

    A timer that specifies the aging time of registered VLANs. If the HVRP designated interface does not receive any registration packets of a VLAN within the aging time, the VLAN is aged on the HVRP designated interface.

HVRP Packet Format

Figure 21-1 shows the HVRP packet format.

Figure 21-1  HVRP packet format

  • Protocol flag: HVRP packet flag bit.
  • Protocol type: HVRP packet type, which can be user VLAN registration or interface status change notification.
  • MSTI ID: Multiple Spanning Tree Instance (MSTI) ID.
  • Packet content: This field is invalid for interface status change notification packets. In user VLAN registration packets, this field contains information about all authorized user VLANs.
