Actually it is standard
Q_USE_PROVIDER_NETWORKING=True
PHYSICAL_NETWORK=providernet
PROVIDER_NETWORK_TYPE=flat
OVS_PHYSICAL_BRIDGE=br-provider
PROVIDER_SUBNET_NAME=provider-subnet
FIXED_RANGE=10.145.253.0/24
NETWORK_GATEWAY=10.145.253.1
ALLOCATION_POOL=start=10.145.253.111,end=10.145.253.242

So earlier, probably the full l3 support wasn't there. I made changes for
logical flow additions in my own repo and use it for testing. I had to do a
big merge for l3 extensions last night because networking-ovn eas expecting
some idl extensions in new updates.

The setup now creates a logical router in OVN and assigns the gateway
address given above. The gateway should not be used to allocate address for
OVN router.

If I create another private network, add a new router attach it to public
network created, the traffic is hitting my external company gateway all the
way out. Not sure what is happening. Can I just delete the default router1
that the devstack setup created? Looks like I may have to do some manual
configs to get this setup working. Or should I disable OVN_L3 in devstack?
