Chapter 2 Advanced Routing for FortiOS 5.0 : Routing Information Protocol (RIP) : Simple RIP example
  
Simple RIP example
This is an example of a typical medium sized network configuration using RIP routing.
Your company has 3 small local networks, one for each department. These networks are connected by RIP, and then connected to the Internet. Each subnet has more than one route, for redundancy. There are two central routers that are both connected to the internet, and to the other networks. If one of those routers goes down, the whole network can continue to function normally.
The ISP is running RIP, so no importing or exporting routes is required on the side of the network. However, since the internal networks have static networking running those will need to be redistributed through the RIP network.
To keep the example simple, there will be no authentication of router traffic.
With RIP properly configured, if the device fails or temporarily goes offline, the routes will change and traffic will continue to flow. RIP is good for a smaller network due to its lack of complex configurations.
