Usage Guidelines

Although these priorities can be changed, do not attempt any manipulation unless you are expertly familiar with the possible consequences. If you change the route priority, you must save the configuration and reboot the system.



The priority for a blackhole route can not overlap with the priority of any other route origin.


The following example sets the IPv6 route priority for static routing to 1200:

configure iproute ipv6 priority static 1200


This command was first available in ExtremeXOS 11.2.
