Hi,
I have followed the Icehouse doc to install a 3 node environment in
CentOS:
http://docs.openstack.org/icehouse/install-guide/install/yum/content/basics-neutron-networking-network-node.html
In my network node, my external NIC is configured witout IP as per the
documentation.
[root@network ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE=eth2
UUID=4a1e4bc2-dac3-4c0a-985a-5a4a2203196e
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
HWADDR=00:0c:29:8d:cc:0a
However I cannot ping the external network (.80 is the virtual router).
[root@network ~]# ping 192.168.50.80
PING 192.168.50.80 (192.168.50.80) 56(84) bytes of data.

From 10.0.0.21 icmp_seq=2 Destination Host Unreachable
From 10.0.0.21 icmp_seq=3 Destination Host Unreachable
This is the info of my environment:
