You are the network engineer responsible for the multi-area OSPF network shown in the exhibit. In order to keep the routing table and LSDB small on the R3 Router in Area 1, and to hide flapping links in other areas, you decide to summarize as much as possible the Area 0 Routes on R1 that are advertised into Area 1. You should include in the summary routes only the following explicit routes:

- 192.168.32.0/24 thru 192.168.39.0/24
- 192.168.48.0/24 thru 192.168.51.0/24

Which configuration will fulfill these requirements?
