Parameters

value: Specifies a multiplier in the range of 3 to 1000.

Usage guidelines

Adjacency hold time sets how long one edge device can retain the adjacency with another. It determines how long it takes for an edge device to detect a failed EVI link.

If the Graceful Restart function is disabled, the adjacency hold time equals the EVI IS-IS hello interval multiplied by the hello multiplier set in this section.

If Graceful Restart is enabled, the adjacency hold time equals the restart interval or the EVI IS-IS hello interval multiplied by the hello multiplier, whichever is greater.

An edge device sends its adjacency hold time in hello packets to update the adjacencies with its neighbor edge devices. A neighbor edge device removes the adjacency with the advertising edge device and recalculates routes if it does not receive an EVI IS-IS hello packet from the advertising edge device before the time value expires.

The maximum adjacency hold time is 65535 seconds. If this value is exceeded, the actual adjacency hold time is set to 65535 seconds.

Examples

# Set the multiplier for calculating EVI IS-IS adjacency holding time to 6.
