what is  point-point link?

 If the physical links are limited to a pair of nodes it is said to be point-point link.

1. On point-to-point links such as High-Level Data Link Control (HDLC) and Point-to-Point Protocol (PPP), Open Shortest Path First (OSPF) runs as a point-to-point network type. This network type is enabled by default. This document shows sample configurations for OSPF over a point-to-point link. The other network types that OSPF supports are Point to Multipoint, Broadcast, and Non-Broadcast.
2. Point-to-point connections are typically used to connect two systems together over a wide area network (WAN). You can use a point-to-point connection to get data from your local system to a remote system or to get data from a local network to a remote network. Do not confuse point-to-point connections with Point-to-Point Protocol. Point-to-Point Protocol (PPP) is one type of a point-to-point connection that is commonly used to connect a computer to the Internet.
