Configuring an OSPF Area

OSPF areas are a collection of subnets that are grouped in a logical fashion. These areas
communicate with other areas via the backbone area. Once OSPF areas are created, you
can add interfaces, stub hosts, and summary ranges to the area.
In order to reduce the amount of routing information propagated between areas, you can
configure summary-ranges on Area Border Routers (ABRs). On the SSR, summary-ranges
are created using the ospf add summary-range command – the networks specified using
this command describe the scope of an area. Intra-area Link State Advertisements (LSAs)
that fall within the specified ranges are not advertised into other areas as inter-area routes.
Instead, the specified ranges are advertised as summary network LSAs.
To create areas and assign interfaces, enter the following commands in the Configure
mode.
Create an OSPF area.
Add an interface to an OSPF area.
