[Fiware-lab-federation-nodes] Does Mirantis fuel 7.0 support GRE tunnels?

[Giuseppe Cossu]

Bruno,
VxLAN is an overlay solution as well, it uses UDP for transporting L2
frames, so it is not required to have a VxLAN compatible switch. My
suggestion is to use the default configuration.
@Spain node: can you confirm that VxLAN can be used? I don't see any issue
on that.

If you want to use GRE you have 2 possibilities:
1) Use the FUEL CLI
https://docs.mirantis.com/openstack/fuel/fuel-7.0/user-guide.html#using-fuel-cli
* e.g.,
fuel env create --name MyEnv --release 2 --mode ha --network-mode neutron
--net-segment-type gre

2) Enabling GRE on /etc/neutron/plugin.ini after the OpenStack deployment.
e.g.,
------------------------------------------------
[ml2]
type_drivers = local,flat,vlan,gre
tenant_network_types = flat,vlan,gre
mechanism_drivers =openvswitch

[agent]
l2_population=False
polling_interval=2
arp_responder=False
dont_fragment=False
tunnel_types=gre
-----------------------------------------------

Regards,
Giuseppe
