Have a single Forest/single Domain with one remote site. A site link was configured between the main site and the remote site.
The main site have two RWDCs (Windows 2016) and no users. Users are located on the remote site which have a RODC. Users are authenticated by the RODC.
I want to create another site and install a RODC there. The goal is: if the RODC fails on the first remote site the users are redirected to the second remote site RODC (using Next Closest Site and NextClosestSiteFilter settings).
My question is in the site links to set up. Do I need the Site Link "Lisboa-DC_RODC" (Sites.png) or just the other two?
