Comment 3 for bug 1522773

You can reproduce it with horizon too creating a network, 2 routers and adding interfaces of both routers to the same network

 I guess the port 27bd30a1-cbd6-4400-a50e-59f52f75ca9e is related to midonet only, if you list the port interfaces from midonet you can see that the port has the address 5.5.5.1

port 27bd30a1-cbd6-4400-a50e-59f52f75ca9e device f19863e5-d4b1-4439-9a9d-0377b3d0d1c7 state up plugged no mac fa:16:3e:d5:25:ff address 5.5.5.1 net 5.5.5.0/24 peer bb8d00af-02c9-4b19-ad4a-c4c2c96eaa6e

However neutron hasn't any port with that UUID and the port that has the 5.5.5.1 is:

| bb8d00af-02c9-4b19-ad4a-c4c2c96eaa6e | | fa:16:3e:d5:25:ff | {"subnet_id": "f754ada3-1381-4ef4-8443-203a423d927c", "ip_address": "5.5.5.1"}
