Explanation
High availability and fast convergence are critical in data center networks to minimize downtime and maintain optimal performance. The following technologies contribute to achieving these goals: Graceful Restart (GR): GR allows routers to maintain forwarding state during control plane restarts, ensuring continuous packet forwarding while minimizing network disruptions. Bidirectional Forwarding Detection (BFD): BFD provides fast detection of path failures, allowing routing protocols to converge quickly by detecting link failures much faster than traditional timers. Link Aggregation Group (LAG): LAG increases both redundancy and bandwidth by combining multiple physical links into one logical link, providing load balancing and fault tolerance.
