Technical Tip: Configure RIP routing protocol in FortiGate

Description

This article allows for a visual guide of RIP configuration in FortiGate GUI on a single FortiGate.

RIP is normally used in small and medium-sized networks.

Scope

FortiGate.

Solution

RIP can be accessed in GUI and these are the available options as default:

For interfaces, use 'Create new' to add all the interfaces involved in RIP traffic.

Use/ enable 'Passive' only for the local LAN interface, for which this unit is the default gateway (no routing table needs to be propagated there).

After this change, it is possible to see the routing protocol being used, and the current settings.

For example:

Redistribution of routes learned via static/ dynamic routing protocols into RIP can be configured from the Advanced options.

RIP will hold the routes for 180 seconds. After that, wait for another two updates and then flush the routes.

Additionally, use the filter list distance to filter the RIP routes.

Instead of redistributing all the connected/static/dynamic routing protocols into the RIP, routemaps should be configured and added to the filter:

For a full configuration of RIP, see the official documentation: Basic RIP example - FortiGate 7.0.4 administration guide.
