1080 CHAPTER 74: IS-IS CONFIGURATION COMMANDS

Description Use the preference command to configure the preference for IS-IS protocol.

Use the undo preference command to restore the default.

By default, the IS-IS protocol 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 set 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.

<Sysname> system-view

[Sysname] isis

[Sysname-isis-1] preference 25
