Underlay Settings

Underlay Settings are used to manage the time and conditions under which network devices detect, respond to, and stabilize after changes in network topology or connection states. In technical networking terms, these could be broadly described as "Network Convergence Timing Controls" - the settings that determine how fast and how precisely a network can detect, communicate, and stabilize after any type of network state change.

The General Underlay Fabric Configuration

Manages fundamental network infrastructure settings, including a shared Anycast MAC address for redundancy and load balancing. It controls how network devices handle address aging and connection restoration, ensuring stable and efficient baseline network communication.

The Spine Underlay Fabric Configuration

Defines how spine devices maintain and establish BGP (Border Gateway Protocol) connections. These settings manage network behaviors such as connection keepalive intervals, connection timeout periods, and routing information exchange.

The Leaf Underlay Fabric Configuration

These settings control how leaf devices establish and maintain BGP connections, including timing for connection checks, routing updates, and connection establishment, ensuring stable and responsive network edge communications.

Data Timer Configuration

Provides advanced timing controls that optimize connection stability and performance. These settings allow network administrators to fine-tune how devices handle interface state changes, link detection, and MAC address management. By adjusting Link State Timeout, Startup Delay, and MAC Holdtime, users can customize network resilience and reduce unnecessary connection disruptions.
