Which statement is true about OSPF Network LSAs?
Select the best response.
A.
They are originated by every router in the OPSF network. They include all routers on the link, interfaces, the cost of the link, and any known neighbor on the link.
B.
They are originated by the DR on every multi-access network. They include all attached routers including the DR itself.
C.
They are originated by Area Border Routers and are sent into a single area to advertise destinations outside that area.
D.
They are originated by Area Border Router and are sent into a single area to advertise an Autonomous System Border Router.
Popular LSA Types are listed below:
LSA Type Description Details
1 Router LSA Generated by all routers in an area to describe their directly attached links
2 Network LSA Advertised by the DR of the broadcast network (does not cross ABR)
3 Summary LSA Advertised by the ABR of originating area
4 Summary LSA Generated by the ABR of the originating area to advertise an ASBR to all other areas in the autonomous system
5 AS external LSA Used by the ASBR to advertise networks from other autonomous systems
7 Defined for NSSAs Generated by an ASBR inside a Not-so-stubby area (NSSA) to describe routes redistributed into the NSSA
I think the answer is C as B is not correct because DR only originates LSAs on Broadcast network and not on Multi-access network which are mainly p2p.
