Given the interface configuration, what is the expected OSPF adjacency state?

The OSPF adjacency will not be established because the OSPF network types are mismatched. Router R1 is configured with ip ospf network point-to-point, while Router R2 is configured with ip ospf network broadcast. For an OSPF adjacency to form, the network types on directly connected interfaces must be compatible. Point-to-point expects only one neighbor, while broadcast expects multiple neighbors and performs DR/BDR elections. This mismatch prevents the routers from successfully exchanging Hello packets and transitioning beyond the Init state. Therefore, no adjacency will be formed.
