7.7 Configuring the IPv4 IS-IS Route Convergence Speed

Accelerating IS-IS route convergence can improve the fault location efficiency and improve the
network reliability.
7.7.1 Before You Start
Before configuring the IPv4 IS-IS route convergence speed, familiarize yourself with the usage
scenario, complete the pre-configuration tasks, and obtain the data required for the configuration.
Applicable Environment
The procedure for implementing IS-IS is as follows:
l
l
l
To accelerate the IS-IS route convergence speed, configure the following parameters:
l
l
l
You can also configure convergence priorities for IPv4 IS-IS routes so that key routes can be
converged by preference when a network topology changes. This minimizes adverse impacts on
key services.
Pre-configuration Tasks
Before configuring the IPv4 IS-IS route convergence speed, complete the following tasks:

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.
