Description of problem:
If we attach a subnet to that external network afterwards, the northbound
database loses that logical port, together with the row in the gateway_chassis table.
Version-Release number of selected component (if applicable):
OSP13 (all versions)
How reproducible:
Always
Steps to Reproduce:
openstack network create public --external --default --provider-network-type vlan --provider-physical-network tenant --provider-segment 1099
openstack router create myrouter
EXT_NET_ID=$(openstack network show public -f value -c id)
openstack router set --external-gateway $EXT_NET_ID myrouter
Actual results:
We lose connectivity on all external subnets, because the router logical port is lost
Expected results:
User should be able to set subnets after creating and attaching external networks to router
Additional info:
See launchpad for more details on what the sequence of events cause this.
