With a few exceptions, creating and managing an HA router is no different from its standalone counterpart. Neutron's router management commands were covered in the previous chapter, and the exceptions can be found in the following sections.
Working with highly available routers
Creating highly-available routers
Users with the admin role can create highly-available routers using the --ha argument with the openstack router create command shown here:
openstack router create --ha ROUTER
Users without the admin role do not have the ability to override the default router type and cannot specify the --ha argument.
