Area ID
The Area ID identifies the subnet area within the OSPF Autonomous System or domain. While its format
is the same as an IP address, it functions only as an identifier and not an address. The 0.0.0.0 area ID
identifies a special area—the backbone—that contains all area border routers.
Area Summary
Check the box to have the OSPF router generate and propagate summary LSAs (Link-State
Advertisements) into OSPF stub areas. LSAs describe the state of the router's interfaces and routing
paths. Stub areas contain only final-destination hosts and do not pass traffic through to other areas.
Sending LSAs to them is usually not necessary. By default this box is not checked.
