CHAPTER 11 ROUTING PROTOCOLS

Routing Strategies

Routing can be done either statically or dynamically.

Static Routing

Static routing is recommended when the network contains a small number of routers and other equipment. When a system is simple and without redundant links, static routing is the simplest option. Even with some redundant links, a multilink circuit can be created for semi-dynamic routing behavior. Multilink circuits are described in section 4.4 of the CyROS Reference Guide.

Dynamic Routing

Dynamic routing is recommended when the network contains a large number or routers with redundant links between them. RIP and OSPF are currently available in the Power Router line. RIP is simpler to configure and is appropriate for systems that are stable (links do not go down often). OSPF is more complicated to configure, requires much more CPU, and is not necessarily available in all equipment in a network. A mixture of RIP, OSPF, and static routes is often used.

BGP-4 is a dynamic routing protocol used to route packets on the Internet. It is used in addition to the protocols RIP and OSPF or static routing.
