Steve, the way I read it is that the tos ophan settings is a replacement for the local clock driver, so I tried to follow the image
of the peer network as shown on the page you linked.
Each of my S2s are synced to a different S1 (using the server line). But also each S2 has a peer line for the other two S2s and the
"tos orphan 5" line.
As a test I disconnected all S1s from the network and let things sit for a while to see what would happen. It has been a while but
if I recall correctly, the S2s dropped down to S5. I do not recall if each S2 chose another S2 as its primary source or what. But
they all continued to distribute time.
If that is configured wrong, then please tell me the correct way and I will happily fix it.
