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

07:57:33.032401 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
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
