/etc/neutron/plugin.ini configure is:
[ml2_type_vlan]
network_vlan_ranges =physnet2:1001:1070,physnet1
When I change 1070 to 2000 and restart neutron-server,the router created
successfully.
network_vlan_ranges is the limit of tenant network number,but
network_vlan_ranges limited the sum of router number and tenat network
number.
I think this is a bug.
