• Area ID—Its length is in the range of 1 to 13 bytes.
• System ID—A system ID uniquely identifies a host or router in the area and has a fixed 6-byte
length.
• SEL—It has a value of 0 and a fixed 1-byte length.
For example, a NET is ab.cdef.1234.5678.9abc.00, where area ID is ab.cdef, system ID is
1234.5678.9abc, and SEL is 00.
Examples
# Specify the NET as 10.0001.1010.1020.1030.00, of which 10.0001 is the area ID and
1010.1020.1030 is the system ID.

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.
Usage guidelines
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 configures 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.
