We are looking to implement a redundant VPN setup but I am not sure on the best way to proceed.
Originally I was looking towards hub-and-spoke but I am conscious about the loss of the central hub site and how to re-establish connections in this case.
Is Fully Meshed the best solution? How does this work in terms of routing and redundant routes?
GRE tunnels? BGP?
What is the best way to proceed?
I hope someone has put in a similar solution and can help!
