Configure network ================= network_cfg.yaml file describes networks configuration for openstack on hosts. It specifies host network mapping and ip assignment of networks to be installed on hosts. Compass4nfv includes a sample network_cfg.yaml under ``compass4nfv/deploy/conf/network_cfg.yaml`` There are three openstack networks to be installed: external, mgmt and storage. These three networks can be shared on one physical nic or on separate nics (multi-nic). The sample included in compass4nfv uses one nic. For multi-nic configuration, see multi-nic configuration. Configure openstack network --------------------------- ****! All interface name in network_cfg.yaml must be identified in dha file by mac address !**** Compass4nfv will install networks on host as described in this configuration. It will look for physical nic on host by **mac address** from dha file and rename nic to the name with that mac address. Therefore, any network interface name that is not identified by mac address in dha file will not be installed correctly as compass4nfv cannot find the nic. **Configure provider network** .. code-block:: yaml provider_net_mappings: - name: br-prv network: physnet interface: eth1 type: ovs role: - controller - compute The external nic in dha file must be named ``eth1`` with mac address. If user uses a different interface name in dha file, change ``eth1`` to that name here. Note: User cannot use eth0 for external interface name as install/pxe network is named as such. **Configure openstack mgmt&storage network**: .. code-block:: yaml sys_intf_mappings: - name: mgmt interface: eth1 vlan_tag: 101 type: vlan role: - controller - compute - name: storage interface: eth1 vlan_tag: 102 type: vlan role: - controller - compute Change ``vlan_tag`` of ``mgmt`` and ``storage`` to corresponding vlan tag configured on switch. **Note**: for virtual deployment, there is no need to modify mgmt&storage network. If using multi-nic feature, i.e, separate nic for mgmt or storage network, user needs to change ``name`` to desired nic name (need to match dha file). Please see multi-nic configuration. Assign IP address to networks ----------------------------------------- ``ip_settings`` section specifics ip assignment for openstack networks. User can use default ip range for mgmt&storage network. for external networks: .. code-block:: yaml - name: external ip_ranges: - - "192.168.50.210" - "192.168.50.220" cidr: "192.168.50.0/24" gw: "192.168.50.1" role: - controller - compute Provide at least number of hosts available ip for external IP range(these ips will be assigned to each host). Provide actual cidr and gateway in ``cidr`` and ``gw`` fields. **configure public IP for horizon dashboard** .. code-block:: yaml public_vip: ip: 192.168.50.240 netmask: "24" interface: external Provide an external ip in ``ip`` field. This ip cannot be within the ip range assigned to external network configured in pervious section. It will be used for horizon address. See section 6.2 (Vitual) and 7.2 (BareMetal) for graphs illustrating network topology.
