Public bug reported: fdsf
** Affects: neutron Importance: Undecided Status: New ** Description changed: - hi, - - When using the command router add subnet <route> <external subnet>, - neutron creates a port with the first IP on the subnet. This causes IP - conflict with the real GW ip for the network, and the result is that the - physical network goes down. In our case it brought down the whole - physical fabric. - - cloud info: - (openstack) network show internet - +---------------------------+--------------------------------------+ - | Field | Value | - +---------------------------+--------------------------------------+ - | admin_state_up | UP | - | availability_zone_hints | | - | availability_zones | nova | - | created_at | 2017-05-10T14:05:08Z | - | description | | - | dns_domain | | - | id | df26cc5b-b122-4506-b948-a213d2b0a7d8 | - | ipv4_address_scope | None | - | ipv6_address_scope | None | - | is_default | False | - | is_vlan_transparent | None | - | mtu | 9000 | - | name | internet | - | port_security_enabled | True | - | project_id | 1642f7380213486aa6b8fefeb179ffd7 | - | provider:network_type | flat | - | provider:physical_network | physnet1 | - | provider:segmentation_id | None | - | qos_policy_id | None | - | revision_number | 7 | - | router:external | External | - | segments | None | - | shared | True | - | status | ACTIVE | - | subnets | cbd1f84a-d31e-4bb3-b788-bacab21f9b6f | - | tags | | - | updated_at | 2017-11-27T00:37:31Z | - +---------------------------+--------------------------------------+ - - (openstack) subnet show internet-sub1 - +-------------------+--------------------------------------+ - | Field | Value | - +-------------------+--------------------------------------+ - | allocation_pools | xxx.yyy.zzz.20-xxx.yyy.zzz.254 | - | cidr | xxx.yyy.zzz.0/24 | - | created_at | 2017-05-10T14:28:46Z | - | description | | - | dns_nameservers | | - | enable_dhcp | True | - | gateway_ip | xxx.yyy.zzz.1 | - | host_routes | | - | id | cbd1f84a-d31e-4bb3-b788-bacab21f9b6f | - | ip_version | 4 | - | ipv6_address_mode | None | - | ipv6_ra_mode | None | - | name | internet-sub1 | - | network_id | df26cc5b-b122-4506-b948-a213d2b0a7d8 | - | project_id | 1642f7380213486aa6b8fefeb179ffd7 | - | revision_number | 3 | - | segment_id | None | - | service_types | | - | subnetpool_id | None | - | tags | | - | updated_at | 2017-05-16T12:02:39Z | - +-------------------+--------------------------------------+ - - - way to reproduce: - 1. As normal _member_ user, create a router - (openstack) router create vpn-client-router - 2. add the external subnet to the router. - (openstack) router add subnet vpn-client-router internet-sub1 - - Actual result: - The port created gets the ip xxx.yyy.zzz.1, which is the same ip as the physical GW IP. - - expected result: - First of all, this command should probably return error since the correct command is router set --external-gateway. If it should work, the IP should be in the allocation_pool for the subnet. - - version: - openstack pike - neutron 11.0.2 - distribution kolla-ansible - - bjolo + fdsf -- You received this bug notification because you are a member of Yahoo!
