CHAPTER 9 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.
Static Routes
Routers used in very small or simple networks may use static routes as the primary routing method. When RIP or
OSPF are used, some static routes may still be needed. Configuration of static routes will be explained using two
examples.
