ipv6 prefix-priority
ipv6 prefix-priority <PREFIX-LENGTHS>
no ipv6 prefix-priority [<PREFIX-LENGTHS>>]
Description
Configures custom IPv6 route prefix lengths for the exact prefix match tables of the switch. The switch must be rebooted to apply the change.
Following the reboot, IPv6 prefix priorities will remain in a pending state until at least one route is learned. A connected route counts so this can be as simple as having an L3 interface with an IP address in the up state.
The no form of this command resets the prefix lengths to their default
