Explains when static routes provide predictable paths for CEF forwarding and why dynamic routing is more suitable for large or frequently changing networks.
A static route is a manually configured route-table entry that
-
defines an explicit path between routers
-
uses less bandwidth than a dynamically calculated route, and
-
requires manual reconfiguration when the network path changes.
Suitable uses
Use static routes in simple networks with predictable traffic or to define a gateway of last resort. Use dynamic routing for large or frequently changing networks.
