Do I have to ensure that interfaces on the two ends of the link are on the same segment and have the same masks during the establishment of the OSPF neighbor relationship

The interfaces on the broadcast network, Non-Broadcast Multi-Access (NBMA) network, and point-to-multipoint (P2MP) network must be on the same network segment and the mask digits on the neighboring interfaces must be consistent. The point-to-point (P2P) network does not have this restriction.
