Chapter 20. OSPF

OSPF is an interior gateway protocol that allows devices connected together in a network to learn the routes that each other has. It works out the best path across a network of routers and links automatically, and handles failures of links and re-routing traffic another way automatically.

The key feature of OSPF is that it is automatic - it allows you to connect routers up in arbitrary ways, each connected to Ethernet subnets and they find each other and distribute routes. It is very simple to use.

It is also useful for connecting to OSPF aware switches, which can help create a network to which FireBricks are also connected.

OSPF is not necessarily fully functional and suggested only for experimental use at present - please do give us feedback.
