Re: [Rdo-list] [Neutron] router can't ping external gateway

There is one thing , which I clearly see . It is qrouter-namespace misconfiguration. There is no qr-xxxxx bridge attached to br-int Picture , in general, should look like this ubuntu@ubuntu-System:~$ sudo ip netns exec qrouter-6cb93ddd-2637-449d-8b10-7c07da49ee8c route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.12.15 0.0.0.0 UG 0 0 0 qg-a753a8f5-c8 10.254.1.0 0.0.0.0 255.255.255.0 U 0 0 0 qr-393d9f71-53 192.168.12.0 0.0.0.0 255.255.255.0 U 0 0 0 qg-a753a8f5-c8 ubuntu@ubuntu-System:~$ sudo ip netns exec qrouter-6cb93ddd-2637-449d-8b10-7c07da49ee8c ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) qg-a753a8f5-c8 Link encap:Ethernet HWaddr fa:16:3e:a2:11:b4 inet addr:192.168.12.150 Bcast:192.168.12.255 Mask:255.255.255.0 inet6 addr: fe80::f816:3eff:fea2:11b4/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:24504 errors:0 dropped:0 overruns:0 frame:0 TX packets:17367 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:24328699 (24.3 MB) TX bytes:1443691 (1.4 MB) qr-393d9f71-53 Link encap:Ethernet HWaddr fa:16:3e:9e:ec:01 inet addr:10.254.1.1 Bcast:10.254.1.255 Mask:255.255.255.0 inet6 addr: fe80::f816:3eff:fe9e:ec01/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:22487 errors:0 dropped:5 overruns:0 frame:0 TX packets:24736 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2379287 (2.3 MB) TX bytes:24338711 (24.3 MB) I would also advise you to post a question also on ask.openstack.org Boris. ------------------------------ Date: Tue, 19 May 2015 09:48:58 +0200 From: ichi.sara(a)gmail.com To: rdo-list(a)redhat.com Subject: [Rdo-list] [Neutron] router can't ping external gateway Hey people, I have an issue with my networking.
