Parameters
preference: Specifies an IS-IS protocol preference in the range of 1 to 255.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters, to assign a priority to the matching routes.
Usage guidelines
If a routing policy is specified in this command, the preference set by the routing policy applies to the
matching routes. Other routes use the preference set by the preference command.
If multiple routing protocols find routes to the same destination, the route found by the routing protocol
with the highest preference is selected as the optimal route.
Examples
# Configure the preference for IS-IS as 25.
<Sysname> system-view
[Sysname] isis 1
