The ipv6 spf-priority command configures a priority for the SPF calculation in an IPv6 base topology.
The undo ipv6 spf-priority command restores the default priority of the SPF calculation in an IPv6 base topology.
By default, the priority of the SPF calculation in an IPv6 base topology is 64.

This command is valid only for an IPv6 base topology.
A higher priority of the 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.
