Route Preferences
The routing table can contain routes from different sources. Routes to a certain
destination can be learned independently from RIP and from OSPF. 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 selection. For example, a high-preference
static default route will not be preferred over a RIP route to the subnetwork of the
destination.
The following list shows P460 protocol preferences from the most to the least
preferred:
1 Local (directly attached network)
2 High-preference static (manually configured routes)
3 OSPF internal routes
4RIP
5OSPF external routes
6 Low-preference static (manually configured routes).
