VRRP

VRRP

The following sections describe configurations of VRRP groups and VRRP parameters. The S1720GFR, S2720, S2750, S5710-X-LI, S5700LI, and S5700S-LI switches do not support the VRRP function.

The Virtual Router Redundancy Protocol (VRRP) is a fault-tolerant protocol. VRRP integrates multiple routing devices into a virtual router and uses certain mechanisms to switch services to other routers when the next hop router fails, ensuring continuous and reliable communication.

VRRP

VRRP switches services from the master to the backup when the gateway becomes faulty, providing continuous and reliable communication services.

Procedure

  • Query VRRP group information.
    1. Choose Service Management > VRRP > VRRP in the navigation tree to open the VRRP page.
    2. Set the search criteria.
    3. Click Query to display all matching records.
  • Create a VRRP group.
    1. Choose Service Management > VRRP > VRRP in the navigation tree to open the VRRP page.
    2. Click Create to open the Create VRRP Group page, as shown in Figure 2-144.

      Figure 2-144  Create VRRP Group

      Table 2-82 describes the parameters on the Create VRRP Group page.

      Table 2-82  Create VRRP Group

      Parameter

      Description

      VRID

      Indicates the ID of a virtual router. This parameter is mandatory.

      VLANIF

      Select a VLANIF interface that requires VRRP configuration. The VLANIF interface must exist in the system.

      Virtual IP

      Indicates the virtual IP address of the VRRP group, for example, 192.168.70.111. This parameter is mandatory.
      NOTE:

      The virtual IP address can be an idle IP address in the network segment of the VRRP group or the IP address of an interface in the VRRP group.

      Preempt mode

      Indicates whether to adopt the preemption mode.
      • If Enable is selected, a backup immediately preempts the Master state when its priority is higher than the master.
      • If Disable is selected, as long as the master is working properly, the backup with higher priority cannot be the master.
      NOTE:
      A larger value indicates a higher priority of the device in a VRRP group.

      Advertisement packet interval

      Indicates the interval for sending VRRP Advertisement packets.

      The master device sends VRRP Advertisement packets to backup devices at intervals to notify the backup devices that it works normally. If the backup devices do not receive any VRRP Advertisement packet within an interval, the backup device with the highest priority becomes the master.

      Configured priority

      Indicates the priority of a member switch.

      The role of each switch in a VRRP group is determined by its priority. The switch with the highest priority becomes the master.

      Monitored Interface

      Interface name

      Indicates the number and type of the tracked interface, for example, GigabitEthernet0/0/1.

      Priority

      Indicates whether to increase or decrease the VRRP priority of the tracked interface when the tracked interface is Down.
      NOTE:

      If the preemption mode is disabled, this parameter cannot be set to Add.

    3. Set parameters.
    4. Click OK.
  • Modify the configuration of a VRRP group.
    1. Choose Service Management > VRRP > VRRP in the navigation tree to open the VRRP page.
    2. Click to open the Modify VRRP Group page, as shown in Figure 2-145.

      Figure 2-145  Modify VRRP Group

      NOTE:
      • Table 2-82 describes the parameters on the Modify VRRP Group page.
      • The VRID and VLANIF interface name cannot be changed.

    3. Set parameters.
    4. Click OK.
  • Delete a VRRP group.
    1. Choose Service Management > VRRP > VRRP in the navigation tree to open the VRRP page.
    2. Select a record that you want to delete and click Delete. The system asks you whether to delete the record.
    3. Click OK.

VRRP Attribute

The following sections describe the configurations of VRRP parameter.

Procedure

  1. Choose Service Management > VRRP > VRRP Attribute in the navigation tree to open the VRRP Attribute page, as shown in Figure 2-146.

    Figure 2-146  VRRP Attribute

    Table 2-83 describes the parameters on the VRRP Attribute page.

    Table 2-83  VRRP Attribute

    Parameter

    Description

    Ping virtual IP

    Indicates whether the ping command can ping the virtual IP address of the VRRP group. The default value is Permit.

    Gratuitous ARP packet sending

    Indicates whether to allow the virtual router to send gratuitous ARP packets. To enable the network elements connected to the virtual router to learn the virtual IP address of the VRRP group, the virtual router needs to send gratuitous ARP packets to the network elements.

    The default value is Permit.

    Gratuitous ARP packet sending interval

    Indicates the interval for sending gratuitous ARP packets.

  2. Set parameters.
  3. Click Apply to complete the configuration.
