Contrasting local and global networks

If all connection network partners are located within the same APPN topology subnetwork, then you can define the connection network as a local connection network (VNTYPE=LOCAL). If some of the connection network partners are in different APPN topology subnetworks, then you must define the connection network as a global connection network (VNTYPE=GLOBAL).

Tip: Some products do not provide a choice between local and global connection networks. In general, if a product supports global connection networks but does not provide a choice of local or global (as part of connection network definition), then any connection networks that are defined are considered global.

Communication between partner nodes in different APPN topology subnetworks using a global connection network requires the assistance of extended border node connections. Based on these considerations, begin planning your EE connection network by drawing a logical diagram of your network showing each connection network and all participating partners.
