7.7.2 Configuring the Interval for Detecting IS-IS Neighboring
Device Failures
To minimize the effects caused by neighboring device failures on an IS-IS network, accelerate
the speed of detecting IS-IS neighboring device failures.
Context
Connection status between an IS-IS device and its neighboring devices can be monitored by
exchanging Hello packets at intervals. An IS-IS neighboring device is considered Down if the
IS-IS device does not receive any Hello packets from the neighboring device within the specified
period (called the holding time). A failure in an IS-IS neighboring device will trigger LSP
flooding and SPF calculation, after which IS-IS routes are reconverged.
To speed up fault detection, use the following methods to accelerate the speed of detecting IS-
IS neighboring device failures:

Data
Interval at which Hello packets are sent and the holding time of neighboring
devices
Flooding time of CSNPs and LSPs
Interval for SPF calculation
Route convergence priority
Shorten the interval at which Hello packets are sent.
Shorten the holding time of neighboring devices.
Configuring Dynamic IPv4 BFD for IS-IS.
NOTE
Configuring IPv4 BFD for IS-IS is recommended because this method provides a faster fault detection
speed than the other two methods.
Set an interval at which Hello packets are sent.
