All the networks involved in the OPNFV +infrastructure as well as the provider networks and the private tenant +VLANs needs to be manually configured. + +Manual configuration of the Brahmaputra hardware platform should +be carried out according to the OPNFV Pharos specification: +<https://wiki.opnfv.org/pharos/pharos_specification> + |
