Allows you to...
This section describes the routing preferences set up according to
the network administrator's preferences. These preferences are
normally set up using the most to least trust. For example, local
routes are normally considered to have more trust or a higher
preference, while OSPF external routes are considered to have less
trust or a lower preference. These preferences can be overridden,
but careful consideration must be given when setting each.
Note:
Local Routes must always have the higher preference.
Note:
Do not change the Prerferences unless you are certain of
the consequences. Incorrect Preference settings can cause
the switch to stop all routing.
Enter a preference value for local routes.
Note:
Local Routes must always have the higher preference.
Enter a preference value for High preference static routes.
Enter an OSPF intra-area route. A lower number indicates a
lower preference for the path.
Enter the inter-area paths to destinations in other OSPF areas.
These are discovered through the examination of received
summary Link State Advertisements (LSA). Enter a number to
specify your path cost. A lower number indicates a lower
preference for the path.
Enter the number of external paths to destinations external to the
Autonomous System (AS). These are detected through the
examination of received AS external LSAs. Enter a number to
specify your path cost (preference). A lower number indicates a
lower preference for the path.
Enter the number of RIP routes to use the hop count as a metric.
Hence, to specify a preference for a RIP route, you need to enter a
lower number (path cost).
Enter a preference value for Low preference static routes.

You can set up a configuration of multiple subnets, and IP interfaces
on a single VLAN. This is also referred to as IP Multinetting. A
network is said to be multinetted when multiple logical groups of
computers are brought together within a single broadcast domain.
In the example (Figure 9-4), two separate networks are brought
