M4300 Intelligent Edge Series Fully Managed Stackable Switches Table 106. Route Configuration - Learned Routes (continued) Field Preference Metric Description The preference is an integer value from 0 to 255. The user can specify the preference value (sometimes called administrative distance) of an individual static route. Among routes to the same destination, the route with the lowest preference value is the route entered into the forwarding database. By specifying the preference of a static route, the user controls whether a static route is more or less preferred than routes from dynamic routing protocols. The preference also controls whether a static route is more or less preferred than other static routes to the same destination. Administrative cost of the path to the destination. If no value is entered, default is 1. The range is 0-255. Specify Route Preferences You can configure the default preference for each protocol, for example, 60 for static routes, 120 for RIP. These values are arbitrary values in the range of 1 to 255 and are independent of route metrics. Most routing protocols use a route metric to determine the shortest path known to the protocol, independent of any other protocol. The best route to a destination is chosen by selecting the route with the lowest preference value. When there are multiple routes to a destination, the preference values are used to determine the preferred route. If there is still a tie, the route with the best route metric is chosen. To avoid problems with mismatched metrics (such as RIP and Open Shortest Path First [OSPF] metrics, which are not directly comparable) you must configure different preference values for each of the protocols. To specify route preferences 1. Launch a web browser. 2. In the address field of your web browser, enter the IP address of the switch. The login window opens. 3. Enter admin as the user name, enter your local device password, and click the Login button. The first time that you log in, no password is required. However, you then must specify a local device password to use each subsequent time that you log in. The System Information page displays. 4.
