I have a client that has approx 7 locations currently using a Metro Ethernet at all locations. The setup is simple and has been working for years. Now my client has dedicated fiber between the sites in a "Ring" configuration. What is the best way to network all the sites together using only Mikrotik routers.. What is the best technique to use? they have 1 public IP network and about 5 private IP networks. im not sure and was hoping for some suggestions?
