ipv6 route prefix-priority-scheduler
Function
The ipv6 route prefix-priority-scheduler command sets the priority-based scheduling weight of IPv6 routes.
The undo ipv6 route prefix-priority-scheduler command restores the default priority-based scheduling weight of IPv6 routes.
By default, the priority-based scheduling weight of IPv6 routes is 8:4:2:1.
Format
ipv6 route prefix-priority-scheduler critical-weight high-weight medium-weight low-weight
undo ipv6 route prefix-priority-scheduler
Parameters
| Parameter | Description | Value |
|---|---|---|
| critical-weight | Sets the scheduling weight of a critical queue. | The value is an integer that ranges from 1 to 10. |
| high-weight | Sets the scheduling weight of a high queue. | The value is an integer that ranges from 1 to 10. |
| medium-weight | Sets the scheduling weight of a medium queue. | The value is an integer that ranges from 1 to 10. |
| low-weight | Sets the scheduling weight of a low queue. | The value is an integer that ranges from 1 to 10. |
Usage Guidelines
Usage Scenario
The integration of network services urgently requires differentiated services. IPv6 routes for key services, such as Voice over IP (VoIP), video conferences, and multicast services, need to be converged rapidly, while routes for common services can be converged relatively slowly. In this case, the system needs to converge IPv6 routes based on their convergence priorities to improve network reliability.
Different IPv6 routes can be set with different convergence priorities, which can be critical, high, medium, and low listed in descending order. Critical is the highest convergence priority; low is the lowest convergence priority. The system converges IPv6 routes based on the convergence priorities and convergence rules, that is, schedules the convergence of IPv6 routes of different convergence priorities in proportion, to guide service forwarding.
When the system is processing a large number of high-priority IPv6 routes, low-priority IPv6 routes may fail to be processed for a long time. In this case, to prevent system performance from being affected, run the ipv6 route prefix-priority-scheduler command to adjust the priority-based scheduling weight of IPv6 routes.
Follow-up Procedure
In most cases, convergence priorities of IPv6 routes are determined by route types. On an ISISv6 network, run the ipv6 prefix-priority (IS-IS) command to adjust the convergence of ISISv6 routes.
