Configure VRRP

This section describes how to configure VRRP on a EX15 device.

Required configuration items

See Configure VRRP+ for information about configuring VRRP+, an extension to VRRP that uses network probing to monitor connections through VRRP-enabled devices and dynamically change the VRRP priorty of devices based on the status of their network connectivity.


  1. Log into Digi Remote Manager, or log into the local Web UI as a user with full Admin access rights.
  2. Access the device configuration:

    1. Locate your device as described in Use Digi Remote Manager to view and manage your device.
    2. Click the Device ID.
    3. Click Settings.
    4. Click to expand Config.

    1. On the menu, click System. Under Configuration, click Device Configuration.

      The Configuration window is displayed.

  3. Click Network > VRRP.
  4. For Add VRRP instance, type a name for the VRRP instance and click .

    The new VRRP instance configuration is displayed.

  5. Click Enable.
  6. For Interface, select the interface on which this VRRP instance should run.
  7. For Router ID field, type the ID of the virtual router instance. The Router ID must be the same on all VRRP devices that participate in the same VRRP device pool. Allowed values are from 1 and 255, and it is configured to 50 by default.
  8. For Priority, type the priority for this router in the group. The router with the highest priority will be used as the master router. If the master router fails, then the IP address of the virtual router is mapped to the backup device with the next highest priority. If this device's actual IP address is being used as the virtual IP address of the VRRP pool, then the priority of this device should be set to 255 . Allowed values are from 1 and 255, and it is configured to 100 by default.
  9. (Optional) For Password, type a password that will be used to authenticate this VRRP router with VRRP peers. If the password length exceeds 8 characters, it will be truncated to 8 characters.
  10. Configure the virtual IP addresses associated with this VRRP instance:
    1. Click to expand Virtual IP addresses.
    2. Click to add a virtual IP address.

    3. For Virtual IP, type the IPv4 or IPv6 address for a virtual IP of this VRRP instance.
    4. (Optional) Repeat to add additional virtual IPs.
  11. See Configure VRRP+ for information about configuring VRRP+.
  12. Click Apply to save the configuration and apply the change.
  1. Select the device in Remote Manager and click Actions > Open Console, or log into the EX15 local command line as a user with full Admin access rights.

    Depending on your device configuration, you may be presented with an Access selection menu. Type admin to access the Admin CLI.

  2. At the command line, type config to enter configuration mode:

    > config
(config)>

  3. Add a VRRP instance. For example:
    (config)> add network vrrp VRRP_test
(config network vrrp VRRP_test)>
  4. Enable the VRRP instance:
    (config network vrrp VRRP_test)> enable true
(config network vrrp VRRP_test)>
  5. Set the interface on which this VRRP instance should run:
    1. (config network vrrp VRRP_test)> interface ?

Interface: The network interface to communicate with VRRP peers on and listen for traffic to virtual IP addresses.
Format:
  /network/interface/setupip
  /network/interface/setuplinklocalip
  /network/interface/lan
  /network/interface/loopback
  /network/interface/modem
  /network/interface/wan
Current value:

(config network vrrp VRRP_test)> interface
    1. Set the interface, for example:
      (config network vrrp VRRP_test)> interface /network/interface/lan
(config network vrrp VRRP_test)>
    2. Repeat for additional interfaces.
  6. Set the router ID. The Router ID must be the same on all VRRP devices that participate in the same VRRP device pool. Allowed values are from 1 and 255, and it is configured to 50 by default. 
    (config network vrrp VRRP_test)> router_id int
(config network vrrp VRRP_test)>
  7. Set the priority for this router in the group. The router with the highest priority will be used as the master router. If the master router fails, then the IP address of the virtual router is mapped to the backup device with the next highest priority. If this device's actual IP address is being used as the virtual IP address of the VRRP pool, then the priority of this device should be set to 255 . Allowed values are from 1 and 255, and it is configured to 100 by default. 
    (config network vrrp VRRP_test)> priority int
(config network vrrp VRRP_test)>
  8. (Optional) Set a password that will be used to authenticate this VRRP router with VRRP peers. If the password length exceeds 8 characters, it will be truncated to 8 characters.
    (config network vrrp VRRP_test)> password pwd
(config network vrrp VRRP_test)>
  9. Add a virtual IP address associated with this VRRP instance. This can be an IPv4 or IPv6 address.
    (config network vrrp VRRP_test)> add virtual_address end ip_address
(config network vrrp VRRP_test)>

    Additional virtual IP addresses can be added by repeating this step with different values for ip_address.

  10. Save the configuration and apply the change.
    (config network vrrp new_vrrp_instance)> save
Configuration saved.

  11. Type exit to exit the Admin CLI.

    Depending on your device configuration, you may be presented with an Access selection menu. Type quit to disconnect from the device.
