VRRP stands for “Virtual Router Redundancy Protocol”. The VRRP provides an automatic assignment of available routers on the same network to a participating host when the “master” router has failed.

This guide shows how to set a VRRP on a Siretta Primary Router so that it acts as a “Master” using a second Siretta Backup Router as a “Backup”.

NOTE: This document applies to all Siretta Routers

The following products have been used to create this document:

  • QUARTZ-W22-UMTS (EU) + ACCESSORIES
  • PC connected to a local area network.
  • 2 x SIM cards, one for each router.
  • QUARTZ-W22-UMTS (EU) + ACCESSORIES

Configure the Primary Router for VRRP

1. Insert SIM card into the Siretta Industrial Router (Example below uses a QUARTZ-W22-UMTS (EU))

2. Enter the APN details as provided by the SIM card provider (You can follow the router Quick Start Guide for more assistance with this).

3. Once the Router is connected to the mobile network you will see the connected status on the router’s web interface (GUI) as seen below.

4. Navigate to the ‘Advanced Network’ > ‘VRRP’ tab on the routers webpage “GUI”

5. Check the “Enable  VRRP” box

6. Select mode as  the “Master”

7. Enter the network IP address of the Backup Router

NOTE: For this example the Backup Router address is set to ‘192.168.1.3’

8. Use the default priority ‘100’ (This can be any number 0-255)

9. Enter the Virtual router ID of your choice (This can be any number 0-255).

NOTE: For this example we have used ‘1’

10. Check the “Authentication” box

11. Enter your chosen password (‘admin’ is the default password)

12. Set the script type as ICMP with address 8.8.8.8

13. Use the default Check Interval ‘3’

14. Use the default Weight ’10’

13. Click save and wait for the router to reboot.

14. Setup is now complete for the Primary Router

Configure the Backup Router for VRRP

1. Navigate to the ‘Advanced Network’ > ‘VRRP’ tab on the routers webpage “GUI”

2. Check the “Enable  VRRP” box

4. Select mode as  the “Backup”

5. Enter the network IP address of the Primary Router

NOTE: For this example the Primary Router address is set to ‘192.168.1.1’

6. Use the default priority ‘100’ (This can be any number 0-255)

7. Enter the Virtual router ID of your choice (This can be any number 0-255).

NOTE: For this example we have used ‘1’ which is what is specified in the Primary Router

8. Check the “Authentication” box

9. Enter your chosen password (‘admin’ is the default password)

10. Set the script type as ICMP with address 8.8.8.8

11. Use the default Check Interval ‘3’

12. Use the default Weight ’10’

13. Click save and wait for the router to reboot.

14. Setup is now complete for the Backup Router

Operation between Primary and Backup Router using VRRP

When the ‘Master’ router cannot send a ping to 8.8.8.8, it will automatically switch to the ‘Backup’ router using the VRRP service. The router will continue to operate on the network but it will use the internet connection of the Backup Router and not the Primary Router.

NOTE: Both the “Master” and the “Backup” router must be on the same network and the same subnet to communicate correctly.
