[Bug 1782026] [NEW] Routed provider network - DHCP agent failure
Public bug reported:
DHCP agent in the network segment in Routed provider network reports the error and does not start dnsmasq process
======
I have routed network based on Mellanox VMS L3 - https://community.mellanox.com/docs/DOC-1432 and a compute nodes on two segments (actually 2 racks with 2 different subnets). I was following the guide on implementing Routed provider networks https://docs.openstack.org/neutron/queens/admin/config-routed-networks.html
======
Rack 1 openvswitch_agent.ini:
[ovs]
bridge_mappings = 40Grack1:br-vlan
Rack 1 openvswitch_agent.ini:
[ovs]
bridge_mappings = 40Grack2:br-vlan
======
Reproduction steps:
openstack network create --project proj --provider-physical-network
40Grack1 --provider-network-type vlan --provider-segment 403 vsorokin-
VLAN403-net
openstack network segment set --name vsorokin-VLAN403-net-rack1
17cf03cb-0165-46c4-9586-598ca2239c75
openstack subnet create --network vsorokin-VLAN403-net --network-segment
vsorokin-VLAN403-net-rack1 --ip-version 4 --subnet-range 10.243.64.0/22
--gateway none --allocation-pool start=10.243.64.2,end=10.243.67.253
--host-route destination=10.243.64.0/18,gateway=10.243.67.254 vsorokin-
VLAN403-subnet-rack1
At this point I can see qdhcp-* netns created and dnsmasq process
running on Rack 1 node.
openstack network segment create --physical-network 40Grack2 --network-
type vlan --segment 403 --network vsorokin-VLAN403-net vsorokin-VLAN403
-net-rack2
openstack subnet create --network vsorokin-VLAN403-net --network-segment
vsorokin-VLAN403-net-rack2 --ip-version 4 --subnet-range 10.243.68.0/22
--gateway none --allocation-pool start=10.243.68.2,end=10.243.71.253
--host-route destination=10.243.64.0/18,gateway=10.243.71.254 vsorokin-
VLAN403-subnet-rack2
That command causes the error in neutron-dhcp-agent.log in the node in Rack 2(repeating every 30 seconds):

As you can see, neutron is trying to make each DHCP agent serving both
subnets. Which I beleive is wrong.

Routed provider network - DHCP agent failure
Status in neutron:
New
Bug description:
DHCP agent in the network segment in Routed provider network reports the error and does not start dnsmasq process
======
I have routed network based on Mellanox VMS L3 - https://community.mellanox.com/docs/DOC-1432 and a compute nodes on two segments (actually 2 racks with 2 different subnets). I was following the guide on implementing Routed provider networks https://docs.openstack.org/neutron/queens/admin/config-routed-networks.html

Rack 1 openvswitch_agent.ini:

======
Reproduction steps:
openstack network create --project proj --provider-physical-network

At this point I can see qdhcp-* netns created and dnsmasq process
running on Rack 1 node.
