[Bug 1585524] [NEW] neutron server Error: TooManyExternalNetworks

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Main steps:
1 create 2 external networks each with a different subnet with neutron CLI commands, there is no error info from CLI.
e.g. neutron net-create --router:external=True --provider:physical_network provider100 --provider:network_type flat provider100
2 create 2 routers connected each of the external net, there is no error info from CLI.
3 create 1 floating ip from one of the external network, no error info from CLI.
4 create 1 private network, and try creating a vm connected to the private network.
there is no response with the command: nova boot xxx.
We can see errors from screen, seems neutron CLI needs more checking when creating more external networks.
