Configuring VRRP on the InRouter302 (IR302)

Set up VRRP on the IR302 to ensure continuous network service in case the primary router fails.

• Two or more IR302 routers.
• Network connectivity among routers participating in VRRP.
• Access to the web interface of the routers.

1. Plan Your VRRP Setup:

   • Determine which router will act as the Master and which will be the Backup.
   • Decide on a Virtual Router ID (VRID) which is unique to the VRRP group.
   • Choose a Virtual IP address that will be used by hosts on the LAN as their default gateway.

2. Configure the Master Router:

   • Log into the web interface of the router designated as the Master.
   • Navigate to Network > VRRP.
   • Click on Add to create a new VRRP group.
   • Enter the Virtual Router ID (VRID).
   • Set the Priority to a higher value (e.g., 100). The Master router should have the highest priority.
   • Enter the Virtual IP address that will be shared among the routers.
   • Save the settings.

3. Configure the Backup Router(s):

   • Log into the web interface of each router designated as a Backup.
   • Navigate to Network > VRRP.
   • Click on Add to join the existing VRRP group.
   • Enter the same Virtual Router ID (VRID) as set on the Master.
   • Set the Priority to a lower value than the Master (e.g., 80).
   • Enter the same Virtual IP address as configured on the Master.
   • Save the settings.

4. Test the VRRP Configuration:

   • Ensure that all routers are correctly configured and connected.
   • From a host on the LAN, set the default gateway to the Virtual IP address.
   • Test connectivity through the default gateway.
   • Simulate a failure of the Master router (e.g., by disconnecting it from the network) and observe if the Backup router takes over seamlessly, ensuring continuous network service.

5. Monitoring and Maintenance:

   • Regularly check the VRRP status on the routers to ensure they are functioning as expected.
   • Monitor network logs for any VRRP-related errors or messages that could indicate problems.

• Always ensure firmware on all VRRP participating routers is up-to-date to avoid compatibility issues.
• Consider setting up em
