The ipv6 spf-priority command configures a priority for SPF calculation in an IPv6 base topology.
The undo ipv6 spf-priority command restores the default priority for SPF calculation in an IPv6 base topology.
By default, the priority of SPF calculation in an IPv6 base topology is 64.
| Parameter | Description | Value |
|---|---|---|
| priority-value | Specifies the priority for SPF calculation in an IPv6 base topology. A larger value indicates a higher priority. | The value is an integer that ranges from 1 to 127. |
A higher priority of SPF calculation in an IPv6 base topology means that the routes in the IPv6 base topology are converged preferentially, which ensures the proper operation of important services.
The ipv6 spf-priority command can take effect only after IPv6 is enabled for the IS-IS process by the ipv6 enable command.
