[rdo-users] RHOSP 10 failed overcloud deployment

[Pedro Sousa]

Hi Anda,

tipically you would use 2 networks:

ctlplane = pxe / dhcp network
external = used for remote connectivity and management of the
undercloud/overcloud nodes (routed network)

You should have at least the external network on director and the
controller nodes. This would be the network you would connect to manage the
overcloud (horizon, openstack endpoints).

See the attached picture.
