As shown above, Local will always be the first choice for routing purposes and the next most reliable path is Static due to
the fact that its has the next lowest value. To set a higher reliability for a route, change its value to a number less than the
value of a route preference that has a greater reliability value using the Current Route Preference Settings window fields.
For example, if the user wishes to make RIP the most reliable route, the user can change its value to one that is less than
the lowest value (Static - 60) or the user could change the other route values to more than 100.
The user should be aware of three points before configuring the route preference:
1. No two route preference values can be the same. Entering the same route preference may cause the switch to crash due
to indecision by the switch.
2. If the user is not fully aware of all the features and functions of the routing protocols on the switch, a change in the
default route preference value may cause routing loops or black holes.
3. After changing the route preference value for a specific routing protocol, that protocol needs to be restarted because the
previously learned routes have been dropped from the switch. The switch must learn the routes again before the new
settings can take affect.
