2、列表
[root@cc07 ~]# neutron router-list +--------------------------------------+----------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------+-------+ | id | name | external_gateway_info | distributed | ha | +--------------------------------------+----------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------+-------+ | 00fede5d-71cf-4c12-b694-88157a503fb5 | routerC | null | False | True | | 2752b0c9-6766-49ed-a044-2e960a38710a | test | null | False | False | | 4fe00052-9158-4ecf-bbd4-ddc28c3ed6da | routerA | null | False | True | | 66d23d4a-472d-41e1-ba98-eee1551c40f1 | hzb-router | null | False | False | | 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 | hzb-route-test | null | False | False | | 75cc932a-4273-49c3-8013-11e50c719858 | wh-router2 | null | False | False | | 9ef43a4b-1e96-4952-9e14-529a90a9b87f | public_router | null | False | False | | a7ed7a6f-efb1-4fc3-95c1-f3048230b2d5 | vpc-router | null | False | False | | bca33800-1ddd-49dc-b6b6-313d72b97018 | wh-router | null | False | False | | d90f3ea9-adc1-48fc-97fb-daa4a51194a8 | test123 | {"network_id": "519386bf-542a-4769-ac87-1b15ab96550c", "enable_snat": true, "external_fixed_ips": [{"subnet_id": "732a6431-e412-4db6-a5ec-bd9913699bab", "ip_address": "172.16.12.211"}]} | False | False | | e8a2d0cb-e27e-46e1-8bef-c727d9da13bc | vpc-router | null | False | False | | e8de4f0e-9a6e-41ba-ad5e-1fa0d215c865 | routerB | {"network_id": "519386bf-542a-4769-ac87-1b15ab96550c", "enable_snat": true, "external_fixed_ips": [{"subnet_id": "732a6431-e412-4db6-a5ec-bd9913699bab", "ip_address": "172.16.12.201"}]} | False | True | | f9670288-6e74-4468-a6f7-695ab8aab986 | wh-router | {"network_id": "519386bf-542a-4769-ac87-1b15ab96550c", "enable_snat": true, "external_fixed_ips": [{"subnet_id": "732a6431-e412-4db6-a5ec-bd9913699bab", "ip_address": "172.16.12.207"}]} | False | False | +--------------------------------------+----------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-------------+-------+
3、创建路由（可以指定tenant-id）
[root@cc07 ~]# neutron router-create hzb-route-test --tenant-id 26a8e1feb372493d831c19d4d9e28d73 Created a new router: +-------------------------+--------------------------------------+ | Field | Value | +-------------------------+--------------------------------------+ | admin_state_up | True | | availability_zone_hints | | | availability_zones | | | description | | | distributed | False | | external_gateway_info | | | ha | False | | id | 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 | | name | hzb-route-test | | routes | | | rx | -1 | | status | ACTIVE | | tenant_id | 26a8e1feb372493d831c19d4d9e28d73 | | tx | -1 | +-------------------------+--------------------------------------+
4、将路由连接到外部网络（hzb-pub1）,设定外部网络网关
[root@cc07 ~]# neutron net-list --tenant-id 26a8e1feb372493d831c19d4d9e28d73 +--------------------------------------+--------------+---------------------------------------------------+ | id | name | subnets | +--------------------------------------+--------------+---------------------------------------------------+ | 0575cad8-38b0-4d0a-833c-86779f4f43bb | hzb-pub1 | | | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | hzb-privnet1 | 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 10.30.0.0/24 | +--------------------------------------+--------------+---------------------------------------------------+
[root@cc07 ~]# neutron router-gateway-set 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 0575cad8-38b0-4d0a-833c-86779f4f43bb Set gateway for router 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 [root@cc07 ~]# neutron router-show 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 +-------------------------+-------------------------------------------------------------------------------------------------------+ | Field | Value | +-------------------------+-------------------------------------------------------------------------------------------------------+ | admin_state_up | True | | availability_zone_hints | | | availability_zones | nova | | description | | | distributed | False | | external_gateway_info | {"network_id": "0575cad8-38b0-4d0a-833c-86779f4f43bb", "enable_snat": true, "external_fixed_ips": []} | | ha | False | | id | 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 | | name | hzb-route-test | | routes | | | rx | -1 | | status | ACTIVE | | tenant_id | 26a8e1feb372493d831c19d4d9e28d73 | | tx | -1 | +-------------------------+-------------------------------------------------------------------------------------------------------+
5、创建内部网络路由接口（绑定子网hzb-sub-net1）
[root@cc07 ~]# neutron subnet-list --network-id=2193270e-c4c9-469c-99ae-87ebdb4ba535 +--------------------------------------+--------------+--------------+----------------------------------------------+ | id | name | cidr | allocation_pools | +--------------------------------------+--------------+--------------+----------------------------------------------+ | 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 | hzb-sub-net1 | 10.30.0.0/24 | {"start": "10.30.0.60", "end": "10.30.0.90"} | +--------------------------------------+--------------+--------------+----------------------------------------------+
[root@cc07 ~]# neutron router-interface-add 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 Bad router request: Subnet for router interface must have a gateway IP. Neutron server returns request_ids: ['req-95b281ad-fe74-41f9-bc5a-0ce8d7064589'] [root@cc07 ~]# [root@cc07 ~]# [root@cc07 ~]# neutron subnet-show 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 +-------------------+----------------------------------------------+ | Field | Value | +-------------------+----------------------------------------------+ | allocation_pools | {"start": "10.30.0.60", "end": "10.30.0.90"} | | cidr | 10.30.0.0/24 | | created_at | 2018-10-25T06:25:23 | | description | | | dns_nameservers | 8.8.8.8 | | enable_dhcp | True | | gateway_ip | | | host_routes | | | id | 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 | | ip_version | 4 | | ipv6_address_mode | | | ipv6_ra_mode | | | name | hzb-sub-net1 | | network_id | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | | subnetpool_id | | | tenant_id | ff2958aa964541679833ddbcc503c5d2 | | updated_at | 2018-10-25T06:42:27 | +-------------------+----------------------------------------------+
出现以上红色字体的错误，是因为子网没有gateway_ip,我们给设置一个
neutron subnet-update 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 --gateway-ip 10.30.0.1
[root@cc07 ~]# neutron router-interface-add 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 Added interface e5add0f4-f3c0-41e0-804a-9f4f63f6eb5e to router 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9. [root@cc07 ~]# [root@cc07 ~]# [root@cc07 ~]# neutron router-show 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 +-------------------------+-------------------------------------------------------------------------------------------------------+ | Field | Value | +-------------------------+-------------------------------------------------------------------------------------------------------+ | admin_state_up | True | | availability_zone_hints | | | availability_zones | nova | | description | | | distributed | False | | external_gateway_info | {"network_id": "0575cad8-38b0-4d0a-833c-86779f4f43bb", "enable_snat": true, "external_fixed_ips": []} | | ha | False | | id | 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 | | name | hzb-route-test | | routes | | | rx | -1 | | status | ACTIVE | | tenant_id | 26a8e1feb372493d831c19d4d9e28d73 | | tx | -1 | +-------------------------+-------------------------------------------------------------------------------------------------------+
6、移除路由接口
[root@cc07 ~]# neutron router-interface-delete 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 Removed interface from router 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9.
7、移除路由的默认网关
移除前：
[root@cc07 ~]# neutron router-show 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 +-------------------------+-------------------------------------------------------------------------------------------------------+ | Field | Value | +-------------------------+-------------------------------------------------------------------------------------------------------+ | admin_state_up | True | | availability_zone_hints | | | availability_zones | nova | | description | | | distributed | False | | external_gateway_info | {"network_id": "0575cad8-38b0-4d0a-833c-86779f4f43bb", "enable_snat": true, "external_fixed_ips": []} | | ha | False | | id | 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 | | name | hzb-route-test | | routes | | | rx | -1 | | status | ACTIVE | | tenant_id | 26a8e1feb372493d831c19d4d9e28d73 | | tx | -1 | +-------------------------+-------------------------------------------------------------------------------------------------------+
[root@cc07 ~]# neutron router-gateway-clear 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 Removed gateway from router 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9
移除后：
[root@cc07 ~]# neutron router-show 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 +-------------------------+--------------------------------------+ | Field | Value | +-------------------------+--------------------------------------+ | admin_state_up | True | | availability_zone_hints | | | availability_zones | nova | | description | | | distributed | False | | external_gateway_info | | | ha | False | | id | 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9 | | name | hzb-route-test | | routes | | | rx | -1 | | status | ACTIVE | | tenant_id | 26a8e1feb372493d831c19d4d9e28d73 | | tx | -1 | +-------------------------+--------------------------------------+
8、删除路由
neutron router-delete 6d61e9a4-76f3-4f33-90b3-21703d7fdfd9
