Description
Using the preference command, you can configure the preference of IS-IS
protocol. Using the undo preference command, you can restore the default value.
Several dynamic routing protocols could run simultaneously on a router. In this
case, there is an issue of sharing and selecting the routing information among all
the routing protocols. The system sets a preference for each routing protocol.
When various routing protocols find the route to the same destination, the
protocol with the higher preference will take effect.
Example
Configure the preference of IS-IS as 25.
[3Com-isis] preference 25

For the related commands, see area-authentication-mode and
