Refer to the Exhibit.
Referring to the exhibit, you are configuring an OSPF network. All OSPF adjacencies come up and
stay stable. But neither R1 nor R2 has the prefix 200.200.200.200/32 in its routing table.

A.
R2 does not have the export policy for prefix 200.200.200.200/32.
B.
R1 does not have routes to network 172.10.1.0/24.
C.
R2 is BDR on both network 172.10.1.0/24 and 172.20.1.0/24.
