I tested this locally and it works for me, meaning I'm not able to delete such a router interface. I also checked the patch https://review.opendev.org/#/c/763198/ and it doesn't reach the part where it tries to delete the interface, it fails much earlier:

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1904751 Title: Neutron – it’s possible to delete router’s port related to external gateway Status in neutron: Invalid Bug description: ### Scenario ### Create a router, set external gateway and add internal interface. List router’s ports and try to delete them. There is a patch you can use in order to reproduce the problem: https://review.opendev.org/#/c/763198/ Note: it's also possible to reroduce the same problem with scenario script (includes VM creation and connectivity check before and after deleting router's port). As expected after port deletion connectivity check fails! Just upload bug.py into the /home/stack/neutron-tempest-plugin on your undercloud host and run it with: python3 -m testtools.run neutron_tempest_plugin.scenario.bug.RoutersTest.test_delete_router ### Actual result ### Port related to external gateway is successfully deleted. ### Expected ### Should fail ### Test patch output in tempest.log ### It's possible to see that the list containing routers port IDs is changed from: ['74abfbfa-3e60-4b6f-971c-5224dd74db2f', 'af0a74a0-2b14-499a-a871-96e5d804da15'] to: ['74abfbfa-3e60-4b6f-971c-5224dd74db2f'] means that the port was deleted. 2020-11-18 10:41:47.998 95480 INFO tempest.lib.common.rest_client [req-cca60a65-1ce0-46f4-8d58-b5177f256115 ] Request (RoutersNegativePolicyTest:test_remove_associated_ports): 200 GET http://10.0.0.109:9696/v2.0/routers/0e7fbc2d-d42b-43d2-873f-5311af9e5c96 0.446s 2020-11-18 10:41:51.676 95480 INFO tempest.lib.common.rest_client [req-1ab5e603-95f9-4cc0-9497-11346dae7c51 ] Request (RoutersNegativePolicyTest:test_remove_associated_ports): 200 PUT http://10.0.0.109:9696/v2.0/routers/0e7fbc2d-d42b-43d2-873f-5311af9e5c96 3.676s 2020-11-18 10:41:55.970 95480 INFO tempest.lib.common.rest_client [req-e51bc925-41d3-46f3-81a3-ff80e5735e9f ] Request (RoutersNegativePolicyTest:test_remove_associated_ports): 200 PUT http://10.0.0.109:9696/v2.0/routers/0e7fbc2d-d42b-43d2-873f-5311af9e5c96/add_router_interface 4.292s 2020-11-18 10:41:56.046 95480 INFO tempest.lib.common.rest_client [req-2fa43806-cbcb-4d3a-93cc-019c98ad2b94 ] Request (RoutersNegativePolicyTest:test_remove_associated_ports): 200 GET http://10.0.0.109:9696/v2.0/ports?router_id=0e7fbc2d-d42b-43d2-873f-5311af9e5c96 0.075s 2020-11-18 10:41:56.047 95480 INFO neutron_tempest_plugin.api.test_routers_negative [-] test_remove_associated_ports ['74abfbfa-3e60-4b6f-971c-5224dd74db2f', 'af0a74a0-2b14-499a-a871-96e5d804da15'] 2020-11-18 10:41:56.128 95480 INFO tempest.lib.common.rest_client [req-fbed6aa9-0d27-47ec-9614-38f72b1ace20 ] Request (RoutersNegativePolicyTest:test_remove_associated_ports): 200 GET http://10.0.0.109:9696/v2.0/ports/74abfbfa-3e60-4b6f-971c-5224dd74db2f 0.080s 2020-11-18 10:41:56.129 95480 INFO neutron_tempest_plugin.api.test_routers_negative [-] test_remove_associated_portsresponse: {'content-type': 'application/json', 'content-length': '898', 'x-openstack-request-id': 'req-fbed6aa9-0d27-47ec-9614-38f72b1ace20', 'date': 'Wed, 18 Nov 2020 15:41:56 GMT', 'connection': 'close', 'status': '200', 'content-location': 'http://10.0.0.109:9696/v2.0/ports/74abfbfa-3e60-4b6f-971c-5224dd74db2f'} 2020-11-18 10:41:56.424 95480 INFO tempest.lib.common.rest_client [req-61c2a22a-0db2-4cbb-a934-671e979d6b44 ] Request (RoutersNegativePolicyTest:test_remove_associated_ports): 409 DELETE http://10.0.0.109:9696/v2.0/ports/74abfbfa-3e60-4b6f-971c-5224dd74db2f 0.294s 2020-11-18 10:41:56.425 95480 ERROR neutron_tempest_plugin.api.test_routers_negative [-] test_remove_associated_portsConflict with state of target resource 2020-11-18 10:41:56.504 95480 INFO tempest.lib.common.rest_client [req-f14dd173-0c96-470c-8bb5-74fb91be1a90 ] Request (RoutersNegativePolicyTest:test_remove_associated_ports): 200 GET http://10.0.0.109:9696/v2.0/ports/af0a74a0-2b14-499a-a871-96e5d804da15 0.078s 2020-11-18 10:41:56.505 95480 INFO neutron_tempest_plugin.api.test_routers_negative [-] test_remove_associated_portsresponse: {'content-type': 'application/json', 'content-length': '892', 'x-openstack-request-id': 'req-f14dd173-0c96-470c-8bb5-74fb91be1a90', 'date': 'Wed, 18 Nov 2020 15:41:56 GMT', 'connection': 'close', 'status': '200', 'content-location': 'http://10.0.0.109:9696/v2.0/ports/af0a74a0-2b14-499a-a871-96e5d804da15'} 2020-11-18 10:41:57.552 95480 INFO tempest.lib.common.rest_client [req-bd795598-b016-4e57-ad95-df53e1fd2fa0 ] Request (RoutersNegativePolicyTest:test_remove_associated_ports): 204 DELETE http://10.0.0.109:9696/v2.0/ports/af0a74a0-2b14-499a-a871-96e5d804da15 1.047s 2020-11-18 10:41:57.652 95480 INFO tempest.lib.common.rest_client [req-2e0dfdeb-5892-40f0-b4a2-ba314ba8fd36 ] Request (RoutersNegativePolicyTest:test_remove_associated_ports): 200 GET http://10.0.0.109:9696/v2.0/ports?router_id=0e7fbc2d-d42b-43d2-873f-5311af9e5c96 0.098s 2020-11-18 10:41:57.653 95480 INFO neutron_tempest_plugin.api.test_routers_negative [-] test_remove_associated_ports ['74abfbfa-3e60-4b6f-971c-5224dd74db2f'] To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/1904751/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
