But what if the elected gateway router fails? In the instance of a failed gateway router, any communications from connected devices destined for the WAN will be stopped, halting any and all traffic from coming in or out of the LAN. Service interruptions such as this can be detrimental to a business, but can be avoided by using what is known as gateway redundancy via a Virtual Router Redundancy Protocol (VRRP). VRRP allows for routers to essentially act as back-ups to one-another in the case of a gateway router failure. In this instance, if one router goes down, another router on the LAN can take the forwarding responsibility of the failed router, allowing for communications to flow uninterrupted to and from the WAN. VRRP functions in creating a virtual gateway router, with its own virtual IP address, to act as the pseudo gateway for the LAN. This virtual gateway router is configured as the gateway router by devices on the LAN, and sends all communication to one of several connected routers, while remaining capable of rerouting communications to a back-up router in a moment’s notice should the initial connected router fail. ## VRRP in the Graphiant Portal From within the Graphiant Portal, you will be able to establish and configure VRRP connections to and between various network Edges under your control. ### Step 1: Locating VRRP in the Graphiant Portal From the Home screen, navigate to the Edge Configuration screen by one of the following: - **Locate the "Configurations" section within the top left of the screen; select 'Configure Edges'.** or - **Click 'Configure' in the sidebar; select 'Devices'.** ![Dashboard overview showing configuration options and usage statistics for network management.](https://cdn.document360.io/d86ecd1c-49f6-4fac-83cc-5e344f28f84f/Images/Documentation/Portal Landing pg 7-25 NEW 'Config'; 'Devices' and 'Configure E's'(4).jpg) This will take you to the ‘Configuration’ page of the Graphiant Portal where you will be able to view all active, staged, and deactivated Edges. From here you will be able to select among the active Edges which Edge(s) you would like to be configured with VRRP. On the left-hand side, **select and click** the Edge you wish to manage under **the column 'Hostname**.' ![Device configuration interface showing activated status and hostname details for DemoEdge.](https://cdn.document360.io/d86ecd1c-49f6-4fac-83cc-5e344f28f84f/Images/Documentation/Screenshot 2026-07-09 at 12.06.28 PM.png) This will take you to a Configuration page with a focus on the Edge you have just chosen. Here you will see a list of headers along the lefthand side of the page, such as ‘Configure Network’, ‘Configure Services’, ‘Configure Policies’, etc. From here, **select and click ‘Configure Network’**. ![Configuration settings for DemoEdge, including network and site details.](https://cdn.document360.io/d86ecd1c-49f6-4fac-83cc-5e344f28f84f/Images/Documentation/Screenshot 2026-07-09 at 12.55.41 PM.png) A dropdown menu will appear. From the dropdown menu, **select and click ‘Interfaces’**. ![Interface settings for DemoEdge, including host name, serial number, and location region.](https://cdn.document360.io/d86ecd1c-49f6-4fac-83cc-5e344f28f84f/Images/Documentation/Screenshot 2026-07-09 at 12.59.57 PM.png) This will take you to the Interfaces page for the chosen Edge. On the Interfaces page, you will see a list of available interfaces to choose from. **On the right-hand side, click the 3 dots indicating more options of the specific interface which you would like to configure VRRP**. From the dropdown menu, **select 'Edit Interface.'** ![Interface management screen displaying various network interface statuses and options.](https://cdn.document360.io/d86ecd1c-49f6-4fac-83cc-5e344f28f84f/Images/Documentation/Screenshot 2026-07-09 at 1.04.48 PM.png) This will bring you to a page dedicated to the interface selected. ![Editing GigabitEthernet1 interface settings including status, type, and IP address configuration.](https://cdn.document360.io/d86ecd1c-49f6-4fac-83cc-5e344f28f84f/Images/Documentation/Screenshot 2026-07-09 at 1.08.20 PM.png) On this page you will be able to manage the selected interface, as well as add a subinterface. > [!NOTE] > Note: > > For instructions on establishing a subinterface, see [Configuring Interfaces](/v1/docs/configuring-interfaces). ### Step 2: Setting up VRRP in the Graphiant Portal Below are instructions for onboarding interfaces on a LAN. Here you will be able to establish a DHCP Relay, toggle Static and DHCP for IPv4 and IPv6 addresses, and establish VRRP. > [!NOTE] > Note: > > For instructions on establishing DHCP Relay, see [**Configuring DHCP Relay**](/v1/docs/configuring-dhcp-relay)**.** At the center of the page dedicated to the selected interface, you will be able to toggle the interface type, with the choice of either ‘LAN’ or ‘WAN’. **Select and click ‘LAN’**. ![Interface type selection for WAN and LAN in network settings documentation.](https://cdn.document360.io/d86ecd1c-49f6-4fac-83cc-5e344f28f84f/Images/Documentation/Screenshot 2026-07-09 at 1.21.44 PM.png) The page will propagate various fields of required information.
