Route Preferences

The routing table may contain routes from different sources. Routes to a certain destination may be learned independently from RIP and from OSPF, and at the same time, a static route can also be configured to the same destination. While metrics are used to choose between routes of the same protocol, protocol preferences are used to choose between routes of different protocols.

The preferences only apply to routes for the same destination IP address and mask. They do not override the longest-match choice. For example, a high-preference static default route will not be preferred over a RIP route to the subnet of the destination.

P330 protocol preferences are listed below from the most to the least preferred: 1 Local (directly attached net)
