Hi Alex, > Is there more info on this 'ens224'?
During a reboot of the container, capturing on the 'outside' ens224 port: [root@base~]# tcpdump -nni ens224 ether src host fe:dd:3f:1e:71:f6 -e tcpdump: WARNING: ens224: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on ens224, link-type EN10MB (Ethernet), capture size 65535 bytes 11:25:10.891717 fe:dd:3f:1e:71:f6 > 33:33:00:00:00:16, ethertype IPv6 (0x86dd), length 90: :: > ff02::16: HBH ICMP6, multicast listener report v2, 1 group record(s), length 28 11:25:10.893931 fe:dd:3f:1e:71:f6 > 33:33:00:00:00:16, ethertype IPv6 (0x86dd), length 90: :: > ff02::16: HBH ICMP6, multicast listener report v2, 1 group record(s), length 28 11:25:11.766548 fe:dd:3f:1e:71:f6 > 33:33:00:00:00:16, ethertype IPv6 (0x86dd), length 90: :: > ff02::16: HBH ICMP6, multicast listener report v2, 1 group record(s), length 28 11:25:11.767396 fe:dd:3f:1e:71:f6 > 33:33:00:00:00:16, ethertype IPv6 (0x86dd), length 90: :: > ff02::16: HBH ICMP6, multicast listener report v2, 1 group record(s), length 28 11:25:11.768703 fe:dd:3f:1e:71:f6 > 33:33:ff:1e:71:f6, ethertype IPv6 (0x86dd), length 78: :: > ff02::1:ff1e:71f6: ICMP6, neighbor solicitation, who has fe80::fcdd:3fff:fe1e:71f6, length 24 11:25:11.768837 fe:dd:3f:1e:71:f6 > 33:33:ff:1e:71:f6, ethertype IPv6 (0x86dd), length 78: :: > ff02::1:ff1e:71f6: ICMP6, neighbor solicitation, who has fe80::fcdd:3fff:fe1e:71f6, length 24 So these frames are srced with the LXC container mac address, being received ingress on the external ens224 interface. I think this is what is tripping up OVS's learning. Hmmm.
