Obviously, the same problem happens with amphora loadbalancers created on tenant networks. The VIP port (ovn virtual port) does not get attached to any chassis and its status remains as "up: false". Raising the severity as this basically means there is no support for amphora loadbalancers with ipv6 VIPs. Testing it for IPv6 VIPs on tenant networks, I checked the status is the same (virtual port with "up: false" and no chassis), but the connectivity from other ports in that tenant network to the IPv6 VIP works. fix posted upstream for review: http://patchwork.ozlabs.org/project/ovn/patch/20210922175755.822094-1-mheib@redhat.com/ fix now available in the upstream ovn. |
Description of problem: When creating an OpenStack Amphora Octavia Loadbalancer in a Neutron Provider Network with IPv6 VIP, there is no connectivity to it. The same works for IPv4, the difference is that for IPv4, the VIP (virtual) port is up and attached to a chassis, while for the IPv6 is down and not associated to the chassis where the LoadBalancer Amphora VM is located. For example: IPv4 SB DB port binding (working): _uuid : 314a8103-4cdb-4c1c-bbbf-608df7e9676c chassis : 5c262ce5-1505-4af5-a829-8b287a8e2c69 datapath : fd056a7c-a911-4050-bc59-c62637fea169 encap : [] external_ids : {name=octavia-lb-b785ea25-dc97-4a5a-b258-dc1238b37dfc, "neutron:cidrs"="172.24.100.25/24 2001:db8::f816:3eff:feaa:d859/64", "neutron:device_id"=lb-b785ea25-dc97-4a5a-b258-dc1238b37dfc, "neutron:device_owner"=Octavia, "neutron:network_name"=neutron-dc32ff2a-758f-4f51-93fb-03e9aee23b0d, "neutron:port_name"=octavia-lb-b785ea25-dc97-4a5a-b258-dc1238b37dfc, "neutron:project_id"="01c910303f864dbe83afffc5d7dad975", "neutron:revision_number"="2", "neutron:security_group_ids"="1b26d73f-409e-43ae-b56a-e203741b4214"} gateway_chassis : [] ha_chassis_group : [] logical_port : "124f2240-3156-42c1-9a44-91256c0938f8" mac : ["fa:16:3e:aa:d8:59 172.24.100.25 2001:db8::f816:3eff:feaa:d859"] nat_addresses : [] options : {mcast_flood_reports="true", requested-chassis="", virtual-ip="172.24.100.25", virtual-parents="f8808210-a7ec-4b83-9d9c-726a6bceb9f1"} parent_port : [] tag : [] tunnel_key : 6 type : virtual up : true IPv6 SB DB port binding (not working): _uuid : 677c40b8-a54b-4dc2-a624-9b1d0f791888 chassis : [] datapath : fd056a7c-a911-4050-bc59-c62637fea169 encap : [] external_ids : {name=octavia-lb-ca702149-a714-4730-b6ab-47ec1581cb69, "neutron:cidrs"="2001:db8::f816:3eff:fe9b:61d1/64", "neutron:device_id"=lb-ca702149-a714-4730-b6ab-47ec1581cb69, "neutron:device_owner" =Octavia, "neutron:network_name"=neutron-dc32ff2a-758f-4f51-93fb-03e9aee23b0d, "neutron:port_name"=octavia-lb-ca702149-a714-4730-b6ab-47ec1581cb69, "neutron:project_id"="01c910303f864dbe83afffc5d7dad975", "neutro n:revision_number"="2", "neutron:security_group_ids"="da6ed914-2017-423e-b5bd-2575dec9e789"} gateway_chassis : [] ha_chassis_group : [] logical_port : "6e214af2-1c7d-4167-b635-ae187ec5102b" mac : ["fa:16:3e:9b:61:d1 2001:db8::f816:3eff:fe9b:61d1"] nat_addresses : [] options : {mcast_flood_reports="true", requested-chassis="", virtual-ip="2001:db8::f816:3eff:fe9b:61d1", virtual-parents="3b2c8f5a-73ba-412d-a83c-1abf817c7b99"} parent_port : [] tag : [] tunnel_key : 8 type : virtual up : false How reproducible: 100%, just create an octavia amphora loadbalancer on a provider network, with an IPv6 VIP.
