I would appreciate it if someone send me any suggestions about CRIO-TSN redundancy functionality (RSTP protocol), because we are trying to develop a High Availability (HA) Data Acquisition System for Hydropower plant.

We are developing a star topology (see image) with TSN for CRIO clock synch, and RSTP for data redundancy, but CISCO told us “IE 4000 has an issue” with RSTP protocol:

We ´d really appreciate if someone could help us with:
how to implement data redundancy in this case?
How to improve our topology?
