That is a little odd, it's left over from a previous stab at doing this as
a flat network rather than tagged.  I certainly don't need it in the
config, but the bond0.2113 device does exist and  is in use, so that may be
a conflict.  I'm trying to reuse the vlan I had for floating IPs  folsom
using FlatDHCP which is also where the node have their public IPs the
controllers is on bond0.2113 (the compute nodes have eht0 untagged on this
vlan and eth1 with , so it may be worth trying this experiment with another
vlan or moving the IP on this vlan to the 1G eth0 interface.

It may also be a namespace issue, I haven't used netns before but
ovs-vswitchd.log is showing lots of errors for the interface the dhcp-agent
for this subnet is on, which makes me suspect a namespace issue:

BTW I also posted this issue at
https://ask.openstack.org/en/question/4119/how-to-configure-direct-public-network-access-with-external-router-and-internal-dhcp-agent/which
has a bit more detailed config info

Thanks,
