Hi Cisco Experts,
I would appreciate it if somebody could confirm if I am correct in what I say here.
I have Area0 which is connected to Area1 and Area2. Area1 and Area2 are not connected to each other.
- Area1 has two ABRs to Area0, abr_A & abr_B - these ABRs are not L3 connected to each other.
- Area2 has one ABR to Area0.
An O (intra-area Type 1 LSA) link from Area 2 is sent into Area0 as an IA link (inter-area Type 3 LSA).
Area0 then propagates this IA link into Area1.
My question is, when the Area0 abr2 propages the IA link (which came from Area2) into Area1 - is it correct to say that Area1 would not propagate this IA link back into Area0 via abr1?
Basically, is it true that when a Type 3 is sent from Area0 into area x - if area x has two ABRs. The other ABR will not then re-send the Type 3 back into Area0.
Thanks!

Alan,
This is correct. The ABR ignores any LSA type 3 received from a non backbone area.
