Refer to the above exhibit. Why are the EIGRP neighbors for this router not learning the routes redistributed from OSPF?（）

• A、Redistribution must be enabled mutually (in both directions) to work correctly.
• B、auto - summary causes the OSPF routes redistributed into EIGRP to be summarized; thus the OSPF network 116.16.34 is summarized to 116.3 4.0.0, which is already covered by the EIGRP protocol.
• C、Default metrics are not configured under EIGRP.
• D、Both routing protocols must have unique autonomous system numbers for redistribution to function correctly.
