Point-to-Point IP Interfaces (ipdptpn)

The point-to-point IP interface for Solstice PPP is /dev/ipdptp. This interface is used to create a direct connection for IP between exactly two hosts, as shown in Figure 1-4.

Figure 1-4 IP Point-to-Point Configuration

A point-to-point IP interface is defined by specifying a source address (or point of attachment) and a unique destination address. There is a single possible destination for the next hop, once the IP datagram has been passed to a given point-to-point interface. Therefore, the same source address can be used for multiple point-to-point connections on the same host. Multiple point-to-point connections can be used to connect to several remote hosts simultaneously.

IP point-to-point connections are supported by both synchronous and asynchronous Solstice PPP links.
