Default level
2: System level
Parameters
preference: Specifies the preference for IS-IS protocol, ranging from 1 to 255.
route-policy route-policy-name: Routing policy name, a case-sensitive string of 1 to 63 characters. The
preference applies to routes passing the routing policy.
Description
Use preference to configure the preference for IS-IS.
Use undo preference to restore the default.
By default, IS-IS preference is 15.
If a routing policy is specified in this command, the preference (if any) set by the routing policy applies
to those matched routes. Other routes use the preference set by the preference command.
When a router runs multiple routing protocols at the same time, the system will configure a preference to
each routing protocol. If several protocols find routes to the same destination, the route of the routing
protocol with the highest preference is selected.
Examples
# Configure the preference of IS-IS protocol as 25.
