The routing table can either be managed manually via static IP routing, or auto-
matically by using dynamic routing protocols, or a combination of both. Static IP
routing is usually fine for small IP networks, or networks with no redundant paths.
To manage routing in larger networks, it is preferred to use dynamic IP routing.
With dynamic routing, the routers will exchange routing information and build
up their routing tables dynamically. Furthermore, dynamic routing utilises net-
work redundancy; if a link goes down, routers will inform each other and packets
will automatically be routed along another path. Thus, dynamic routing proto-
cols perform a similar service in routed networks as FRNT (

chapter 14

) and RSTP

(

chapter 16

) perform in switched networks. The time to react on a topology

change is referred to as the convergence time. WeOS supports two dynamic
routing protocols: Open Shortest Path First (OSPF) and Routing Information Pro-
tocol (RIP). OSPF is the recommended over RIP, due to its superior convergence
characteristics.

OSPF and RIP are examples of unicast Interior Gateway Protocols (IGPs), which
means they can be used to handle routing within a routing domain, such as an
corporate network. This is also referred to as intra-domain routing, as opposed
inter-domain routing, which is commonly handled using the Border Gateway Pro-
tocol (BGP)

. OSPF and RIP are covered in

chapters 27

and

respectively.

As of WeOS v4.17.0, dynamic routing is limited to intra-domain (unicast) routing with RIP and

OSPF. WeOS does not support dynamic inter-domain routing via BGP (Border Gateway Protocol), or
