True or False: GRE tunnels should always be deployed in pairs for redundancy?

Deploying GRE (Generic Routing Encapsulation) tunnels in pairs for redundancy is a best practice in network design. This approach ensures high availability and resilience in the network. If one GRE tunnel goes down due to a failure or maintenance, the other tunnel can continue to handle traffic, preventing interruptions in communication and preserving the integrity of data transmission.

Implementing redundancy through paired tunnels also helps load balancing and provides a seamless experience for users and applications relying on the network. In environments with critical applications or services, such redundancy is essential to maintain business continuity and reduce potential downtime.

This practice aligns with the principles of robust network architecture, where fault tolerance is prioritized to enhance the reliability of network services. Therefore, stating that GRE tunnels should always be deployed in pairs aligns with the goal of creating a dependable network infrastructure capable of sustaining operational demands.
