High Availability Switching
Networking vendors love promoting novel overly complex technologies instead of solving their customers' challenges with good network design. High-availability switching (the ability to continue packet forwarding during a control plane failure) is no exception.
Mechanisms
Interaction With Other Control-Plane Protocols
