I'd check the external network config first. You should be able to ping the external subnet's gateway from the router namespace. This gateway should correspond to some real external gateway/router.
quantum subnet-show <ext sub id> -c gateway_ip # 10.245.124.1 ? ip netns exec <router-ns> ping -c1 <ext sub gateway> If that is not working use tcpdump as you ping. Br-ex is using eth0, is eth0 up? tcpdump -nei eth0 If you are still having problems, post the above output and the following: # network node ip link ip netns exec <router-ns> ip address quantum net-show <uuid of external net> quantum subnet-show <uuid of external subnet> >________________________________ > From: Farhan Patwa <farhan.pa...@utsa.edu> >To: OpenStack Maillist <openstack@lists.launchpad.net> >Sent: Friday, 24 May 2013, 20:28 >Subject: [Openstack] VM Issues on Grizzly Install on Ubuntu 12.04 > > > >Hello, >I followed the following guide to install Grizzly release on 3-node setup. >http://docs.openstack.org/grizzly/basic-install/apt/content/basic-install_intro.html > > >I am stuck at my last issue with Quantum networking (at least that’s what I >think). >The VM instance comes up and gets the private IP and the metadata. >Also I have assigned the floating IP to it but am not able to ping either IP >except when I use: > > >ip netns exec qrouter-32f35fb4-f9f1-4817-8818-fff832f73810 ping 50.50.1.3 > <- fixed IP – private network >ip netns exec qrouter-32f35fb4-f9f1-4817-8818-fff832f73810 ping 10.24.124.4 ><- floating IP – external network > > >Based on that I think the security rules are okay >The router is tied to the specified tenant and using gateway of the external >network. >I think the issue is routing table or maybe firewall related but not sure how >to debug this. > > >Some details of my environment are below. >Any one have any words of wisdom/guidance? > > >Thanks, > > >-Farhan. > > >Management Network: 192.168.0.0/24 >Data Network: 10.5.5.0/24 >External Network: 10.245.124.0/24 > > >Network Node: (192.168.0.2) >ovs-vsctl show >ea4fa894-5986-40f2-b10b-55eef2222408 > Bridge br-tun > Port patch-int > Interface patch-int > type: patch > options: {peer=patch-tun} > Port "gre-1" > Interface "gre-1" > type: gre > options: {in_key=flow, out_key=flow, remote_ip="192.168.0.3"} > Port br-tun > Interface br-tun > type: internal > Bridge br-int > Port "tap3fca71a9-c8" > tag: 4095 > Interface "tap3fca71a9-c8" > type: internal > Port patch-tun > Interface patch-tun > type: patch > options: {peer=patch-int} > Port "tap4b8a22a2-9c" > tag: 4095 > Interface "tap4b8a22a2-9c" > type: internal > Port "tap633ed611-a9" > tag: 1 > Interface "tap633ed611-a9" > type: internal > Port "qr-eebfe1cb-0f" > tag: 1 > Interface "qr-eebfe1cb-0f" > type: internal > Port br-int > Interface br-int > type: internal > Bridge br-ex > Port "eth0" > Interface "eth0" > Port br-ex > Interface br-ex > type: internal > Port "qg-910fef3b-cb" > Interface "qg-910fef3b-cb" > type: internal > ovs_version: "1.4.0+build0" > > >Kernel IP routing table >Destination Gateway Genmask Flags Metric Ref Use Iface >0.0.0.0 192.168.0.253 0.0.0.0 UG 0 0 0 eth1 >10.5.5.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 >10.245.124.0 0.0.0.0 255.255.255.0 U 0 0 0 br-ex >192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 > > >Compute Node: (192.168.0.3) >ovs-vsctl show >f0fe78a5-dfd0-4f6b-87be-466dac0b4473 > Bridge br-tun > Port patch-int > Interface patch-int > type: patch > options: {peer=patch-tun} > Port br-tun > Interface br-tun > type: internal > Port "gre-2" > Interface "gre-2" > type: gre > options: {in_key=flow, out_key=flow, remote_ip="192.168.0.2"} > Bridge br-int > Port patch-tun > Interface patch-tun > type: patch > options: {peer=patch-int} > Port br-int > Interface br-int > type: internal > Port "tap6514a8cc-b2" > tag: 1 > Interface "tap6514a8cc-b2" > ovs_version: "1.4.0+build0" > > >Kernel IP routing table >Destination Gateway Genmask Flags Metric Ref Use Iface >0.0.0.0 192.168.0.253 0.0.0.0 UG 0 0 0 eth1 >10.5.5.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 >10.245.124.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 >192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 > > >_______________________________________________ >Mailing list: https://launchpad.net/~openstack >Post to : openstack@lists.launchpad.net >Unsubscribe : https://launchpad.net/~openstack >More help : https://help.launchpad.net/ListHelp > > > _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
