Views OSPF view Predefined user roles network-admin Usage guidelines RFC 1583 specifies a different method than RFC 2328 for selecting the best route from multiple AS external routes destined for the same network. Using this command makes them compatible. If RFC 2328 is compatible with RFC 1583, the intra-area route in the backbone area is preferred. If not, the intra-area route in the non-backbone area is preferred to reduce the burden of the backbone area. Examples # Disable compatibility with RFC 1583. system-view [Sysname] ospf 100 [Sysname-ospf-100] undo rfc1583 compatible router id Use router id to configure a global router ID. Use undo router id to restore the default. Syntax router id router-id undo router id Default No global router ID is configured. Views System view Predefined user roles network-admin Parameters router-id: Specifies the router ID, in the format of an IPv4 address. Usage guidelines OSPF uses a router ID to identify a device. If no router ID is specified, the global router ID is used. If no global router ID is configured, the highest loopback interface IP address is used as the router ID. If no loopback interface IP address is available, the highest physical interface IP address is used, regardless of the interface status (up or down). A new router ID is selected only when the interface IP address used as the router ID is removed or changed. Other events will not trigger a router ID re-selection. For example, router ID re-selection is not triggered when the interface goes down, you change the router ID to the address of a loopback interface after a physical interface address is selected as the router ID, or a higher interface IP address is configured as the router ID. After a router ID is changed, you must use the reset command to enable it. 124
