11.4. 创建中继连接
要为 VLAN 标记的流量实施中继，请创建一个父端口并将新端口附加到现有的 neutron 网络。当您附加新端口时，OpenStack 网络会添加您所创建的父端口的中继连接。接下来，创建子端口。这些子端口将 VLAN 连接到实例，允许连接到中继。在实例操作系统中，还必须创建一个子接口，用于标记与子端口关联的 VLAN 的流量。
识别包含需要访问中继 VLAN 的实例的网络。在本例中，这是 公共网络 ：
openstack network list +--------------------------------------+---------+--------------------------------------+ | ID | Name | Subnets | +--------------------------------------+---------+--------------------------------------+ | 82845092-4701-4004-add7-838837837621 | private | 434c7982-cd96-4c41-a8c9-b93adbdcb197 | | 8d8bc6d6-5b28-4e00-b99e-157516ff0050 | public | 3fd811b4-c104-44b5-8ff8-7a86af5e332c | +--------------------------------------+---------+--------------------------------------+
创建父中继端口，并将它附加到实例连接的网络中。在本例中，在公共网络上 创建一个名为 parent-trunk-port 的 neutron 端口。此中继是 父 端口，您可以使用它来创建 子端口。
openstack port create --network public parent-trunk-port +-----------------------+-----------------------------------------------------------------------------+ | Field | Value | +-----------------------+-----------------------------------------------------------------------------+ | admin_state_up | UP | | allowed_address_pairs | | | binding_host_id | | | binding_profile | | | binding_vif_details | | | binding_vif_type | unbound | | binding_vnic_type | normal | | created_at | 2016-10-20T02:02:33Z | | description | | | device_id | | | device_owner | | | extra_dhcp_opts | | | fixed_ips | ip_address='172.24.4.230', subnet_id='dc608964-9af3-4fed-9f06-6d3844fb9b9b' | | headers | | | id | 20b6fdf8-0d43-475a-a0f1-ec8f757a4a39 | | mac_address | fa:16:3e:33:c4:75 | | name | parent-trunk-port | | network_id | 871a6bd8-4193-45d7-a300-dcb2420e7cc3 | | project_id | 745d33000ac74d30a77539f8920555e7 | | project_id | 745d33000ac74d30a77539f8920555e7 | | revision_number | 4 | | security_groups | 59e2af18-93c6-4201-861b-19a8a8b79b23 | | status | DOWN | | updated_at | 2016-10-20T02:02:33Z | +-----------------------+-----------------------------------------------------------------------------+
使用在第 2 步中创建的端口创建中继。在本例中，中继名为
parent-trunk。openstack network trunk create --parent-port parent-trunk-port parent-trunk +-----------------+--------------------------------------+ | Field | Value | +-----------------+--------------------------------------+ | admin_state_up | UP | | created_at | 2016-10-20T02:05:17Z | | description | | | id | 0e4263e2-5761-4cf6-ab6d-b22884a0fa88 | | name | parent-trunk | | port_id | 20b6fdf8-0d43-475a-a0f1-ec8f757a4a39 | | revision_number | 1 | | status | DOWN | | sub_ports | | | tenant_id | 745d33000ac74d30a77539f8920555e7 | | updated_at | 2016-10-20T02:05:17Z | +-----------------+--------------------------------------+
