A little more information, or a completely different problem...I just
realized my network node can't ping its public gateway. (Instead of
7.7.7.0/24, I am using 10.42.36.0/23. My gateway is .1 (and has
non-redundant IP of .10), and my Network Node IP is .130). This did work
at one time.
root@os-network:~# ping 10.42.36.1

Nor does it work the other way:

I suppose something has gone wrong inside quantum on the network node? Is
there a good way to blow everything away and rebuild? I tried the
following, but the quantum-networking script doesn't really work this way,
as it assumes it is creating items (and getting the uuids in return), which
doesn't work the second time through.
ovs-vsctl del-br br-int
ovs-vsctl del-br br-ex
service openvswitch-switch restart
ovs-vsctl add-br br-int
ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex eth2
ip link set up br-ex
service quantum-plugin-openvswitch-agent restart
service quantum-dhcp-agent restart
service quantum-l3-agent restart
sh ./quantum-networking-filled.sh
service quantum-l3-agent restart
Here is what quantum looks like right now-- note the additional
provider-routers, I'm guessing from failed runs of the quantum-networking
script. Note also ...771's external gateway of ...3de0, which isn't
showing up anywhere...could that be the problem? Should that be subnet
...06f6?
