value: Specifies the preference, ranging from1 to 255. By default, the value is 15.
Description
Use the preference command to configure the preference of IS-IS protocol.
Use the undo preference command to 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
