Cisco® Field Manual: Catalyst® Switch Configuration

5-6. Routing Tables

• To move packets between separate networks, the switching processor must have knowledge of the destination network.

• Networks that are connected to a physical or virtual interface are connected routes and are automatically known by the switching processor.

• You can configure the Layer 3 switching processor with statically defined routes by entering the routes into the configuration file.

• One of the most common ways to learn and maintain routes is to use a dynamic routing protocol, such as Open Shortest Path First (OSPF) Protocol or Enhanced Interior Gateway Routing Protocol (EIGRP).
