End Node Directory

Potential partner LUs in the APPN network do not need to be defined to the end node. However, in order for Node EN3 to establish a session with LUX on Node LEN1, the LU on the LEN node must be configured as a partner LU on Node EN3.

Network Node Directories. A network node provides distributed directory services to the end nodes it serves.

An example of a network node directory is shown in Figure 1-7, “Network Node Directory.”
