Hi,

Is it possible to use the same Network node to manage both VLAN and GRE setup.

Thanks.

What OS you intend to run on Network Node ?

Yes. If tenant_network_type=gre then when a tenant creates a network they will get a GRE backed network. But the provider/admin can still create VLAN backed networks by specifying the provider attributes when creating the network with the CLI.

I would guess that admin's network should have shared status to be available for whoever ,but not admin
and hence cannot be allocated for particular tenant or I am wrong ?

Yes, the admin can create a shared network that all tenants can use. Or the admin can create a network for a specific tenant by specifying the tenant's ID, e.g. neutron net-create net1 --tenant-id $TENANT_ID --provider:network_type vlan --provider:physical_network vlan_net1 --provider:segmentation_id 100

Thank you for clarification and command line syntax.

I believe answer is no for at least Neutron  OVS&VLAN or OVS&GRE setups
File /etc/neutron/plugin.ini -> /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini  (on CenOS 6.5 and Fedora 20)
has entry 
tenant_network_type = gre 
or
tenant_network_type = vlan
for OVS plugin (my experience is obviously limited). So you should have two OVS plugins on the same Neutron Server and separate /etc/neutron/plugin.ini for each plugin.
