Is there a limitation of network created in openstack?

On creating a network each tap interfaces at the br-int are associated to each vlan on OVS. It indicates that there are one-to-one mappings between VLAN IDs and GRE/VXLAN tunnel IDs.

Does it mean the range of tunnel_ids is limited by VLAN tags? Can we create only 4094 networks?

Does In detail, When i create a network, a tap interface is created in br-int with a VLAN associated to it mean in the range of tunnel_ids neutron node. So if i create 100 networks, then 100 tap interfaces will be created with 100 vlan-id's associated with each other. If this is limited by VLAN tags? the way it works, then Can we create only 4094 networks?4096 networks,since on creating 4097th network, the VLAN may be exhausted?

Please reply what will happen specific to neutron node? because this wont be a issue at compute node.
