So an ISP wants me to set up a secure site-to-site VPN between A, B, C and ensuring redundancy such that A can reach C if B is down and so on.
Their Diagram
Router A, B, C all have public IP of the same subnet/prefix
They want to set up site-to-site in order to for the internal network of A, B, C to be accessible by each and any of the sites. For example, those in A can access B, those in B can access C and C and access A etc.
So what would be the optimal solution for this? Which VPN protocol can ensure good performance along with redundancy? I've looked at MikroTik docs/guides/forums but most of them only talk about IPSec with two sites.
I would definitely need some implementation examples/help on this one.
