HI everyone,
i installed Openstack juno all-in-one in a single VM using the RDO packstack. i configured the external bridge to meet the configuration of my environment then i wanted to create the external network from the begining so i deleted the default network and also the router. when i tried to create a new external network i encounter the error :

create failed (client error): Invalid input for operation: network_type value 'flat' not supported.


the log of network server shows
