4.2.1 Configuring Router ID
Router ID is a 32-bit unsigned integer in IP address format that uniquely identifies a
router within an AS. Router ID can be configured manually. If router ID is not configured,
the system will select the IP address of an interface automatically. When you do that
manually, you must guarantee that the IDs of any two routers in the AS are unique. A
common undertaking is to set the router ID to be the IP address of an interface on the
router.
Perform the following configuration in system view.
