Subject: Two flat networks
To: "openstack at lists.openstack.org" <openstack at lists.openstack.org>


Hi,

I was able to solve all the problems that I had with getting one flat
network in the same subnet as I have a router in - 192.168.22.0/24.
Instances successfully get IP addresses in the desired pool and the
communication works perfectly.

As an "upgrade" to that I still want to use my public IP subnet (
102.203.103.80/29) directly on the instances.

I have now changed two lines in ovs_neutron_plugin.ini to:
network_vlan_ranges = physnet1,physnet2
bridge_mappings = physnet1:br-em1,physnet2:br-em2

and created new bridge br-em2 on compute and controller nodes.

I have connected em2 to a separate port on the HW switch.

Network and subnet via neutron are created successully (network is using
physnet2) and I can ping the hw router's default gateway from DHCP server's
namespace:

However, there are absolutely no DHCP DISCOVER messages from the instance
in the syslog as they are for the first flat network.

I can see in neutron's server.log that two physnets (physnet1 and physnet2)
are created successfully and since the first one is working I have no ideas
why the second - physnet2 doesn't.

Any ideas on where to look and what to do will be very welcome :)
TIA, Matej
