(Optional) Setting the Mode in Which VRRP Advertisement Packets Are Sent in a Super-VLAN

(Optional) Setting the Mode in Which VRRP Advertisement Packets Are Sent in a Super-VLAN

Context

When a VRRP group is configured in a super-VLAN, configure VRRP Advertisement packets to be sent to a specified sub-VLAN. This configuration ensures that Advertisement packets are not broadcast in all sub-VLANs, reducing the demand for network bandwidth.

Prerequisites

A super-VLAN has been configured.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface vlanif vlan-id

    The VLANIF interface view is displayed.

  3. Run vrrp advertise vlan { sub-vlan-id | all }

    A mode in which VRRP Advertisement packets are sent in a super-VLAN is set.

    By default, the master sends VRRP Advertisement packets to a sub-VLAN that is Up and has the smallest VLAN ID in a super-VLAN.

    • If sub-vlan-id is specified, the master sends VRRP Advertisement packets to a specified sub-VLAN.

    • If all is specified, the master broadcasts VRRP Advertisement packets to all sub-VLANs of a super-VLAN.

    NOTE:
    • If all is specified, the master broadcasts VRRP Advertisement packets to all sub-VLANs of a super-VLAN, increasing the CPU usage. Therefore, do not specify all.

    • When VRRP is configured in a super-VLAN on a switch excluding the CE6870EI and CE6875EI, the switch will deliver virtual MAC address entries of all sub-VLANs in the super-VLAN.

      • On the CE8800, CE7800, CE6800, and CE5800 series switches (excluding the CE6810LI), there are only 512 virtual MAC address entry resources. The entries are shared by the VLANIF interface and TRILL as bridge MAC addresses. It is recommended that the number of virtual MAC addresses used by VRRP be within 500.

  4. Run commit

    The configuration is committed.
