Answer / rajiv
AS (Autonomous System) are used in EIGRP and BGP
protocols . It is the collection of routers under a common
administrative domain.
Area is used in OSPF to minimize the routing updates.
Routers within an area can not advertise the routing
updates to differenet area Router. ABR is used to advertise
the routes between different area (inter area routes)

AS autonomous system number which is use in EIGRP ,
bydefault same as no can communicate to each other it is
used for security .
Area no , it is used in OSPF router same area no can
communicate each other here it is used for fast
communication and security .

AS is a set of rules to communicate interior gateway
protocols with exterior gateway protocol like eigrp and bgp
while area is define that it is the division of networks in

Answer / anonymous
AS: Autonomous system, this is a collection of routers
(links) that belong to a single administrative domain, used
by EIGRP to communicate between devices, also you can break
a single EIGRP AS, Ex: AS10 for policy based routing,
effectively changing the dist metric from 90 Ext to 170 Int
BGP also uses AS to break admin domains for routing.
Area is used in OSPF SPF algorithm, this area, either ABR,
or ASBR router will flood Link state advertisements ( Type
1,2,3,5,7) which gives a topoloigical view of the network.
OSPF uses different area types, stub NSSA,Totally stubby
area (Area-No Stummary) to filter LSA's.
You need all areas (routers links in those areas) to be
contigous to Area0 (Backbone area).
