PROBLEM OR CPNFUSION WITH OSPF SUMMARY ROUTES

Good, it’s my first post here in the forum.

My drawback is that I would like to know if the following is possible:

I want the ABR of AREA1 to publish all the routes of that area to AREA2 but with a single prefix, ex: 10.10.0.0/20.

When I make the configuration in the ABR of AREA1, it only summarizes the networks that are directly connected to it, which are: 10.10.10.1/30, 10.10.10.5/30 and 10.10.10.10/30, it does not summarize the IR LANs that they are: 10.10.11.1/24, 10.10.12.1/24 and 10.10.13.1/24.

I enclose an image so they can see and understand the scenario and topology.

Thanks in advance.
