Hello Larry,
If you do not have any TCP/IP (internet/intranet) connection between the Local and SYSPLEX1 systems, z/OSMF running in each of the Sysplexes will not be able to communicate, so there isn't much point in trying to define the remote Sysplexes in the respective z/OSMF Systems app of each Sysplex.
Normally, a single z/OSMF server is run on one z/OS system in any given Sysplex. So in your case, I would expect z/OSMF to be started on one of the z/OS systems in Local and one of the systems in SYSPLEX1. On the z/OSMF in Local, after opening the Systems app, you may find it already populated. If not, you can run discovery and it should create a Sysplex entry for Local and add all z/OS members of Local to the Sysplex entry. The same should be the case for SYSPLEX1.
In the Systems app on Local, you can manually create a Sysplex and system entries for SYSPLEX1 and its z/OS systems. Similarly, on SYSPLEX1 you can manually create a Sysplex and system entries for Local and its z/OS systems. When you do this, you should identify the z/OSMF endpoint URL in the z/OS system entry that host z/OSMF on the remote Sysplex.
