<div>Hi Miguel,</div>
<div><br>
</div>
<div>An external network should really be a vlan or flat network that has some external gateway in your environment. Although sometimes gre and vxlan network types are defined in the external provider network configuration, it's usually seen when the external
bridge is br-ex (default) and the bridge is not handled by OVS (meaning there are no flows). Ultimately, the interface in br-ex handles how traffic gets tagged and the provider attributes are ignored.</div>

</div>
<div>Hope that helps.</div>

<div>I'm wondering if it is possible to create multiple external networks mixing gre and flat types.
<br>
<br>
This is the current schema of networks:<br>
<i>internal networks -> gre</i><i><br>
</i><i>em2 -> gre</i><i><br>
</i><i>p3p1 -> flat</i><br>
<br>
These are the configuration files<br>
<b>plugin.ini</b><br>
<br>
<small><small>[ml2]<br>
type_drivers = gre, flat<br>
...<br>
[ml2_type_flat]<br>
flat_networks = p3p1<br>
...<br>
<br>
[ovs]<br>
local_ip = 111.0.0.1<br>
tunnel_type = gre<br>
enable_tunneling = True<br>
network_vlan_ranges = p3p1<br>
bridge_mappings = p3p1:br-ex-p3p1 (<b>only flat</b><b> ??</b>)</small></small><br>
<br>
<b>l3_agent.ini</b><br>
<small><small>...<br>
gateway_external_network_id = <br>
handle_internal_only_routers = True<br>
external_network_bridge =</small></small><br>
<br>
After this configuration, only new routers attached to gre external networks are not pingable from outside. The instances can ping to router but not outside.<br>
<br>
The routers created under flat network work fine.<br>
<br>
Any idea to integrate/repair flat and gre external networks together?<br>
