Configuring OSPF Area

OSPF uses area to implement the hierarchical routing. OSPF areas
are divided into stub area, totally stubby area and not-so-stubby
area. Backbone area is a transitional area.

Configuring Inter-Area Route
Aggregation
Route aggregation can occur between areas or autonomous sys-
tems (AS). Inter-area route aggregation takes place on the ABR
whereas inter-AS route aggregation happens on the ASBR.
Configuring a stub area can save resources on routers in the stub
area but it does not help the backbone area.
If network addresses in an area are allocated in sequence, config-
ure ABR to advertise an aggregate route to replace the sequential
routes. Route aggregation can save resources in the backbone
area by advertising a summary address for a group of network
addresses.
Function
This configures interface priority.
Function
This designates the neighbor
routers on a non-broadcast.
Function
This defines an area as a stub
area or totally stubby area.
This defines an area as a
not-so-stubby area.
