• 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 of ab.cdef.1234.5678.9abc.00 specifies the area ID ab.cdef, the system ID
1234.5678.9abc, and the SEL 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 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.
