Public bug reported:
The static route removes the local route from qrouter-namespace routing
table.
I created two networks with subnet:
First:
#openstack network create Network-1 -f value -c id
784615c9-f9c4-4f4e-87d8-7e5dc76fde5e
#openstack subnet create sub-v4 --network 784615c9-f9c4-4f4e-87d8-7e5dc76fde5e
--subnet-range 192.168.0.0/24 -f value -c id
0f1f9cfd-0956-46bd-9bcc-c6eca6fa522b
Second:
#openstack network create Network-2 -f value -c id
041011cc-e254-4326-afa7-9951686610fc
#openstack subnet create sub-v4 --network 041011cc-e254-4326-afa7-9951686610fc
--subnet-range 172.16.0.0/24 -f value -c id
3a500e8f-9ef8-48de-a148-623d7fa8e580
Create router:
openstack router create Router-Openstack -f value -c id
3d9e5161-0c19-4bcd-abb8-9350bfcefb56
Added subnet to router:
#openstack router add subnet 3d9e5161-0c19-4bcd-abb8-9350bfcefb56
0f1f9cfd-0956-46bd-9bcc-c6eca6fa522b
#openstack router add subnet 3d9e5161-0c19-4bcd-abb8-9350bfcefb56
3a500e8f-9ef8-48de-a148-623d7fa8e580
I now have a router with two interfaces.

Why is it still showing the wrong entry in the routing table and the local

I believe that after deleting the route, the routing entry should look like
