Comprehensive and Detailed in-depth Step-by-Step Explanation:

To answer this question, it is essential to distinguish between the roles of ABRs and ASBRs in OSPF and the function of route summarization:

Route Summarization on ABRs:

Route summarization in OSPF can reduce the number of inter-area Type 3 LSAs that ABRs propagate between areas.

ABRs perform route summarization to reduce the amount of routing information exchanged between areas, thereby decreasing the size of the routing table and improving resource utilization.

Route Summarization on ASBRs:

ASBRs summarize external routes (from outside OSPF) into Type 5 LSAs or Type 7 LSAs (in NSSAs).

ASBR route summarization does not impact inter-area Type 3 LSAs because ASBRs are responsible for importing and summarizing external routes , not summarizing routes between OSPF areas.

Since the statement refers to configuring route summarization on ASBRs to reduce inter-area Type 3 LSAs , it is incorrect . Route summarization for inter-area Type 3 LSAs must be configured on ABRs, not ASBRs.

Correct Statement: Route summarization on ABRs reduces the number of inter-area Type 3 LSAs.
