Populating the Routing Tables 
The switch maintains a set of IP routing tables for both network routes and host routes. Some 
routes are determined dynamically from routing protocols, and some routes are manually 
entered. When multiple routes are available to a destination, configurable options such as 
route priorities, route sharing, and compressed routes are considered when creating and 
updating the routing tables. This section presents the following topics:
Dynamic Routes
Dynamic routes are typically learned by enabling the RIP, OSPF, or BGP protocols, and are 
also learned from Internet Control Message Protocol (ICMP) redirects exchanged with other 
routers. These routes are called dynamic routes because they are not a permanent part of 
the configuration. The routes are learned when the router starts up and are dynamically 
updated as the network changes. Older dynamic routes are aged out of the tables when an 
update for the network is not received for a period of time, as determined by the routing 
protocol.
