OK, one step closer to this but still not quite there... in ovs_neutron_plugin.ini on my network node I have:<br>
<br>
tenant_network_type = vlan<br>
network_vlan_ranges = physnet1:200:209,Extnet<br>
bridge_mappings = physnet1:br-eth2,Extnet:br-ex<br>
<br>
and when I run this command I get an error:<br>
<br>
# neutron net-create ext-net --provider:network_type=flat --provider:physical_network Extnet --shared --router:external=True<br>
<br>
400-{u'NeutronError': {u'message': u'Invalid input for operation: Unknown provider:physical_network Extnet.', u'type': u'InvalidInput', u'detail': u''}}<br>
<br>
I'm not sure how it's not seeing that Extnet isn't there, I defined it in the plugin.ini file on the network node... On the controller node I even tried to put that same plugin.ini info in there (even though the controller node doesn't have br-eth2) as a test, still doesn't work. Any ideas where it's not finding "physical_network Extnet"? I think I'm very close here but just am an inch away...<br>
<br>
Thanks again!<br>

Maruf was correct.<br>
<br>
Also in your plugin.ini you have associate each physical network to a<br>
bridge. And each of those bridges should have one physical network<br>
interface attached.<br>
<br>
In my previous mail i gave an example where I associated Extnet to<br>
br-ex. Then add eth2 to br-ex. Then your external network(ext-net) would<br>
be overlaid on top of Extnet, bridged to br-ex, then traffic flows<br>
outside through eth2.<br>
<br>
Thank you,<br>

You need to use 'flat' instead of 'local' and specify physical_network .<br>
so modify<br>
<br>
neutron net-create ext-net --provider:network_type=local --shared<br>
--router:external=True<br>
<br>
to<br>
<br>
neutron net-create ext-net --provider:network_type=flat<br>
--provider:physical_network Extnet --shared --router:external=True<br>
<br>
Extnet is the name you configured in plugin.ini as bridge_mapping<br>

kind of detail...<br>

Make your external network flat. If you do so there wont be any<br>
vlan tag<br>
on packets reaching your external network.<br>
<br>
in you plugin.ini you put something like this<br>
network_vlan_ranges = Intnet1:100:200,Extnet<br>
bridge_mappings = Intnet1:br-eth1,Extnet:br-ex<br>
<br>
This means you would use vlan id 100 to 200 on openstack networks<br>
created on top of Intnet1.<br>
<br>
On Extnet you would not use any vlan.<br>
<br>
Then you say that to all traffic on network created on Intnet1<br>
should be<br>
bridged to br-eth1. Then you would add eth1 to br-eth1.<br>
<br>
Then you say all traffic for Extnet should be bridged to br-ex.<br>
Then you<br>
have to add a physical interface say eth2 to br-ex.<br>
<br>
Finally you can create an external network in openstack with<br>
physical_network=Extnet.<br>
<br>
You just said that all internal network shall be created and<br>
Intnet1 and<br>
allocated vlan from 100 to 200.<br>
External network shall be overlaid on top of Extnet and no vlans.<br>
<br>
Hope it makes sense.<br>

<br>
Hey Y'all,<br>
<br>
I'm setting up a dedicated neutron network node and I'm<br>
having a bit<br>
of trouble understanding the way the networks work. On the<br>
network<br>
node I have one interface on the public net (eth0), one<br>
interface on<br>
the private net (eth1) and I'm following these guides to<br>
set it up.<br>
<br>
My plan is to have eth0 on the public network, no VLAN<br>
magic there<br>
or anything. eth1 will be the data interface, and it will be<br>
connected to a trunk switchport so it can use VLANs for tenant<br>
isolation (OVS VLAN plugin).<br>
<br>
I ran this command to set up ext-net:<br>
<br>
neutron net-create ext-net --router:external=True<br>
<br>
Created a new network:<br>

<br>
<br>
<br>
But, I don't think network_type=vlan right? As eth0 just<br>
sits right<br>
on a public network? Should network_type=local instead? Also,<br>
should physical_network equal null, and also<br>
segmentation_id equal<br>
null as well?<br>
<br>
I would understand type=vlan and seg_id and such for a tenant<br>
network, but for ext-net?<br>
<br>
Any hints would be greatly appreciated...!<br>
