You can also configure convergence priorities for IPv6 IS-IS routes so that key routes can be
converged by preference when a network topology changes. This minimizes adverse impacts on
key services.

7.16.2 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
Issue 02 (2014-09-30)
Establishment of neighboring relationships: establishes neighboring relationships by
exchanging Hello packets between two devices.
LSP flooding: implements LSDB synchronization between devices in the same area.
SPF calculation: uses the SPF algorithm to calculate IS-IS routes, and delivers the IS-IS
routes to the routing table.
Interval for detecting IS-IS neighboring device failures.
Flooding parameters of CSNPs and LSPs.
Interval for SPF calculation.
Configuring the link layer protocol on interfaces.
Configuring IP addresses for interfaces to ensure that neighboring nodes are reachable at
the network layer.
