6.15.1 Establishing the Configuration Task

Before configuring the IPv6 IS-IS route convergence speed, familiarize yourself with the
applicable environment, complete the pre-configuration tasks, and obtain the data required for
the configuration. This will help you complete the configuration task quickly and efficiently.
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 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.
Pre-configuration Tasks
Before configuring the IPv6 IS-IS route convergence speed, complete the following tasks:
l

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.
