Hi, I am new to openstack deployements and I am trying to make an icehouse setup on opensuse 13.1. with repository http://download.opensuse.org/repositories/Cloud:/OpenStack:/Icehouse/openSUS... But I am stuck on the neutron configuration. I think I have set it up according to http://docs.openstack.org/icehouse/install-guide/install/zypper/content/ch_n... However I am not able to ping the router of the external net configured in neutron ext-net. Here is what happens external net: 172.16.0.0/24 physical router 172.16.0.1 the neutron router of the ext-net: 172.16.0.110 ping from 172.16.0.21 to 172.16.0.110 On physical nic tcpdump -ieno1 07:58:22.540247 ARP, Request who-has 172.16.0.110 tell 172.16.0.21, length 46 07:58:22.964585 ARP, Request who-has 172.16.4.35 tell 172.16.4.1, length 46 07:58:23.032330 ARP, Request who-has 172.16.0.96 tell 172.16.0.99, length 46 on bridge tcpdump -ibr-ex 07:57:32.535197 ARP, Request who-has 172.16.0.110 tell 172.16.0.21, length 46 07:57:32.616321 ARP, Request who-has 172.16.0.98 tell 172.16.0.99, length 46 07:57:33.032401 ARP, Request who-has 172.16.0.96 tell 172.16.0.99, length 46 on router ip netns exec qrouter-24ab9088-6283-4053-a78f-61feb56d4e63 tcpdump -iany tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on any, link-type LINUX_SLL (Linux cooked), capture size 65535 bytes <empty/nothing> I am confused here, The only thing I find strange is the router port is connected to the br-int and not the br-ex, (see output of vs-vsctl show below) Any help would be very helpful. mfg, Jeroen ovs-dpctl dump-flows skb_priority(0),in_port(4),eth(src=78:24:af:2c:09:5e,dst=ff:ff:ff:ff:ff:ff),eth_type(0x0806),arp(sip=172.16.0.21/255.255.255.255,tip=172.16.0.110/255.255.255.255,op=1/0xff,sha=78:24:af:2c:09:5e/00:00:00:00:00:00,tha=00:00:00:00:00:00/00:00:00:00:00:00), packets:23, bytes:1380, used:0.239s, actions:3 phoenix:~ #
