Hi,Jesoph.

    I can’t understand your Qn2,can you detail the topology further?

    How can R1 both receive a network LSA and originate one?

    Best regards,

    Jacky Ping

Hi,

As it looks like mostly R2 will not add the network route(inter area) for the summary lsa it recvs from R1, because it already has a Intra area route to the same 

network , so it should not generate the summ lsa for the network back to area 2.

Suggest you verify !

        Hi All,

        Consider this topology:

        [Area 0] - - - - R1 - - - - [Area 2] - - - - R2 - - - - [Area 0]

        When R1 receives a Network LSA from an internal router in Area 2, it summarises it into Area 0.  This Summary LSA is seen by R2 since it has an interface in the backbone.

        Qn 1) Will R2 import this Summary LSA into Area 2? 

        Qn 2) If R1 comes across a self-originated Summary LSA for the same Network in Area2 with a lower cost, what should it do?

        Regards,

        Joseph Placid
