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 convergence priorities to IPv6 IS-IS routes. Convergence priority levels are critical, high,
medium, and low. The higher the convergence priority, the faster the convergence speed.
By default, IPv6 IS-IS host routes have medium convergence priority, and other IPv6 IS-IS routes
have 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.
Specify an IS-IS cost style.
4.
Enter IPv6 address family
view.
5.
Enable IPv6 IS-IS MTR.
6.
Assign
priority to specific IPv6 IS-IS
routes.
