When You removed and added again br-ex it has no any openflow rules configured. So there will be no traffic passed via this bridge at all please try to restart neutron-openvswitch-agent and check if rules are recreated. If that will help, You can apply patch https://review.openstack.org/#/c/573696/ and check if that will help :) > ovs-vsctl add-port br-ex eth3 > ifconfig br-ex 10.4.13.104 netmask 255.255.255.0 > route add -net 10.4.0.0 netmask 255.255.0.0 gateway 10.4.13.1 dev br-ex > > > On Network node: > > [2018-06-18 11:38:24] root@h004:~$ ip netns exec > qdhcp-eb7573a0-9d91-491c-b150-90f0135778ad ping 12.12.0.4 > PING 12.12.0.4 (12.12.0.4) 56(84) bytes of data. > 64 bytes from 12.12.0.4: icmp_seq=1 ttl=64 time=1.98 ms > 64 bytes from 12.12.0.4: icmp_seq=2 ttl=64 time=0.529 ms > ^C > --- 12.12.0.4 ping statistics --- > 2 packets transmitted, 2 received, 0% packet loss, time 1001ms > rtt min/avg/max/mdev = 0.529/1.254/1.980/0.726 ms > [2018-06-18 11:38:33] root@h004:~$ ip netns exec > qdhcp-eb7573a0-9d91-491c-b150-90f0135778ad ssh cirros@12.12.0.4 > ^C > [SSH Not working] > > [2018-06-18 11:45:51] root@h004:~$ ip netns exec > qrouter-d770b552-1979-4063-ae79-c6ff402c8cbc traceroute 8.8.8.8 > traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets > connect: Network is unreachable > [2018-06-18 11:58:01] root@h004:~$ ip netns exec > qrouter-d770b552-1979-4063-ae79-c6ff402c8cbc traceroute 12.12.0.4 > traceroute to 12.12.0.4 (12.12.0.4), 30 hops max, 60 byte packets > > > On Compute node: > [2018-06-18 11:56:12] root@h011:~$ ip netns exec > qrouter-d770b552-1979-4063-ae79-c6ff402c8cbc traceroute 8.8.8.8 > traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets > connect: Network is unreachable > > [2018-06-18 11:59:20] root@h011:~$ ip netns exec > qrouter-d770b552-1979-4063-ae79-c6ff402c8cbc ping 12.12.0.4 > PING 12.12.0.4 (12.12.0.4) 56(84) bytes of data. > 64 bytes from 12.12.0.4: icmp_seq=1 ttl=64 time=1.61 ms > 64 bytes from 12.12.0.4: icmp_seq=2 ttl=64 time=0.273 ms > ^C > --- 12.12.0.4 ping statistics --- > 2 packets transmitted, 2 received, 0% packet loss, time 1001ms > rtt min/avg/max/mdev = 0.273/0.943/1.614/0.671 ms > [2018-06-18 12:02:21] root@h011:~$ ip netns exec > qrouter-d770b552-1979-4063-ae79-c6ff402c8cbc ping x.x.170.61 (floating ip) > connect: Network is unreachable > > > > -- > P SAVE PAPER – Please do not print this e-mail unless absolutely necessary. > _______________________________________________ > Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack > Post to : openstack@lists.openstack.org > Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack — Slawek Kaplonski Senior software engineer Red Hat _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
