The concept of an Autonomous System is carried in the AREA(S) used by OSPF.
There are 4 things which enable OSPF routers to become adjacent in the same
area.
Area Identification
Authentication
Hello and Dead Intervals
Stub Area Flag
However, the AS may consist of several areas arranged in a hierachy with
Area 0 at the top.
The AS can seen as a group of one or more areas under the same
administration.
The router process-id only identifies a particular separate algorithm of
OSPF. There can be more than one OSPF process running on the same routers in
the same area.
Hope it helps.
Winston.
