Command History
Usage Guidelines Use the ip ospf database command to display information about different OSPF LSAs.
When the link state advertisement is describing a network, the link-state-id argument can take one of two
forms:
• The network’s IP address (such as Type 3 summary link advertisements and autonomous system
external link advertisements).
• A derived address obtained from the link state ID. (Note that masking a network links
advertisement’s link state ID with the network’s subnet mask yields the network’s IP address.)
• When the link state advertisement is describing a router, the link state ID is always the described
router’s OSPF router ID.
• When an autonomous system external advertisement (LS Type = 5) is describing a default route, its
link state ID is set to Default Destination (0.0.0.0).
This command requires the LAN Enterprise Services license.
