19.2.1 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.
Table 19-1 Configure router ID
Operation Command
Configure router ID router id router-id
Remove the router ID undo router id
To ensure stability of OSPF, the user should determine the division of router IDs and
manually configure them when planning the network.
