提供商网络¶
提供商（外部）网络将实例桥接到提供第 3 层服务的物理网络基础设施。在大多数情况下，提供商网络使用 VLAN ID 实现第 2 层分段。提供商网络映射到每个计算节点上的提供商桥接，该桥接支持启动提供商网络上的实例。您可以创建多个提供商桥接，每个桥接都需要一个唯一的名称和底层的物理网络接口，以防止交换环路。提供商网络和桥接可以使用任意名称，但每个映射必须引用有效的提供商网络和桥接名称。每个提供商桥接可以包含一个 flat（未标记）网络，以及物理网络基础设施支持的最多数量的 vlan（标记）网络，通常约为 4000 个。
创建提供商网络涉及主机、OVS 和网络服务级别上的多个命令，这些命令会在 OVN 级别产生一系列操作，以创建虚拟网络组件。以下示例创建了一个使用提供商桥接 br-provider 的 flat 提供商网络 provider，并将其绑定到一个子网。
创建提供商网络¶
在每个计算节点上，创建提供商桥接，将提供商网络映射到它，并将底层的物理或逻辑（通常是绑定）网络接口添加到它。
# ovs-vsctl --may-exist add-br br-provider -- set bridge br-provider \ protocols=OpenFlow13 # ovs-vsctl set Open_vSwitch . external-ids:ovn-bridge-mappings=provider:br-provider # ovs-vsctl --may-exist add-port br-provider INTERFACE_NAME
将
INTERFACE_NAME替换为底层网络接口的名称。注意
如果成功，这些命令不会产生任何输出。
在控制器节点上，激活管理项目凭据。
在控制器节点上，要启用此底盘来托管外部连接的网关路由器，请将 ovn-cms-options 设置为 enable-chassis-as-gw。
# ovs-vsctl set Open_vSwitch . external-ids:ovn-cms-options="enable-chassis-as-gw"
注意
如果成功，此命令不会产生任何输出。
在控制器节点上，在网络服务中创建提供商网络。在这种情况下，其他项目中的实例和路由器可以使用该网络。

注意
--provider-physical-network的值必须引用映射中的提供商网络名称。
OVN 操作¶
OVN 机制驱动程序和 OVN 在创建提供商网络期间执行以下操作。
机制驱动程序将网络转换为 OVN 北向数据库中的逻辑交换机。
_uuid : 98edf19f-2dbc-4182-af9b-79cafa4794b6 acls : [] external_ids : {"neutron:network_name"=provider} load_balancer : [] name : "neutron-e4abf6df-f8cf-49fd-85d4-3ea399f4d645" ports : [92ee7c2f-cd22-4cac-a9d9-68a374dc7b17] .. note:: The ``neutron:network_name`` field in ``external_ids`` contains the network name and ``name`` contains the network UUID.
此外，由于提供商网络由单独的桥接处理，因此在 OVN 北向数据库中创建以下逻辑端口。
_uuid : 92ee7c2f-cd22-4cac-a9d9-68a374dc7b17 addresses : [unknown] enabled : [] external_ids : {} name : "provnet-e4abf6df-f8cf-49fd-85d4-3ea399f4d645" options : {network_name=provider} parent_name : [] port_security : [] tag : [] type : localnet up : false
OVN 北向服务将这些对象转换为 OVN 南向数据库中的数据平面绑定、端口绑定和适当的多播组。

在提供商网络上创建子网¶
提供商网络至少需要一个包含实例可用的 IP 地址分配、默认网关 IP 地址以及名称解析等元数据的子网。
在控制器节点上，创建一个绑定到提供商网络
provider的子网。$ openstack subnet create --network provider --subnet-range \ 203.0.113.0/24 --allocation-pool start=203.0.113.101,end=203.0.113.250 \ --dns-nameserver 8.8.8.8,8.8.4.4 --gateway 203.0.113.1 provider-v4 +-------------------+--------------------------------------+ | Field | Value | +-------------------+--------------------------------------+ | allocation_pools | 203.0.113.101-203.0.113.250 | | cidr | 203.0.113.0/24 | | created_at | 2016-06-15 15:50:45+00:00 | | description | | | dns_nameservers | 8.8.8.8, 8.8.4.4 | | enable_dhcp | True | | gateway_ip | 203.0.113.1 | | host_routes | | | id | 32a61337-c5a3-448a-a1e7-c11d6f062c21 | | ip_version | 4 | | ipv6_address_mode | None | | ipv6_ra_mode | None | | name | provider-v4 | | network_id | 0243277b-4aa8-46d8-9e10-5c9ad5e01521 | | project_id | b1ebf33664df402693f729090cfab861 | | subnetpool_id | None | | updated_at | 2016-06-15 15:50:45+00:00 | +-------------------+--------------------------------------+
如果使用 DHCP 来管理实例 IP 地址，添加子网会在网络服务和 OVN 中产生一系列操作。
网络服务会在适当数量的 DHCP 代理上调度网络。示例环境包含三个 DHCP 代理。
每个 DHCP 代理都会生成一个使用来自子网分配的 IP 地址的网络命名空间，并运行一个
dnsmasq进程。OVN 机制驱动程序为每个
dnsmasq进程在 OVN 北向数据库中创建一个逻辑交换机端口对象。
OVN 操作¶
OVN 机制驱动程序和 OVN 在提供商网络上创建子网期间执行以下操作。
如果子网使用 DHCP 进行 IP 地址管理，则为服务于该子网的每个 DHCP 代理创建逻辑端口，并将它们绑定到逻辑交换机。在此示例中，该子网包含两个 DHCP 代理。
