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.
