Tuning and optimizing IPv6 IS-IS networks

Configuration prerequisites

Before you tune and optimize IPv6 IS-IS networks, complete basic IPv6 IS-IS tasks.

Assigning a convergence priority to IPv6 IS-IS routes

A topology change causes IS-IS routing convergence. To improve convergence speed, you can assign
different convergence priorities to specific IPv6 IS-IS routes, including critical, high, medium, and low.
The higher the convergence priority, the faster the convergence speed.
By default, IPv6 IS-IS host routes have the medium convergence priority, and other IPv6 IS-IS routes have
the low convergence priority.
To assign a convergence priority to specific IPv6 IS-IS routes:
Step
1.
Enter system view.
2.
Enter IS-IS view.
3.
Assign a convergence priority
to specific IPv6 IS-IS routes.

Configuring BFD for IPv6 IS-IS

Bidirectional forwarding detection (BFD) can quickly detect faults between IPv6 IS-IS neighbors to
improve the convergence speed of IPv6 IS-IS. For more information about BFD, see High Availability
Configuration Guide.
To configure BFD for IPv6 IS-IS:
Step
1.
Enter system view.
2.
Enable an IS-IS process and
enter IS-IS view.
3.
Configure the NET for the IS-IS
process.
4.
Enable IPv6 for the IS-IS
process.
5.
Return to system view.
6.
Enter interface view.
7.
Enable IPv6 for an IS-IS
process.
