[Bug 1938023] Re: Cannot delete vlan type network via network generic switch (ngs)
Hello:
The provider information is added to the network dictionary in [1]. If
the number of segments in a network is 1, the provider information will
be set in the network dictionary. If the number of segments is >1, the
provider information will be written in network['segments'] = [...].
You are probably hitting this issue.
I'll add "networking_generic_switch" to this bug to make this project
aware of this problem.
Regards.

Title:
Cannot delete vlan type network via network generic switch (ngs)
Status in Networking ML2 Generic Switch :

Bug description:
User cannot delete vlan type network via network generic switch:
how to reproduce:
1.Create network - works fine - NGS is able to create vlans on switch
openstack network create test-network
2.Delete network - Is not failing via CLI - however goes too quickly - error log in neutron-server (pasted below)
openstack network delete test-network
neutron stable/victoria - It seems that something had changed in
neutron between those two versions (the same NGS version):
working neutron version:
$ pip list | grep -E "neutron|generic-switch"
networking-generic-switch 4.0.1.dev3
neutron 17.1.2.dev36
neutron-dynamic-routing 17.0.1.dev3
neutron-fwaas 16.0.0
neutron-lib 2.6.1
neutron-vpnaas 17.0.1.dev4
python-neutronclient 7.2.1
not working neutron version:
$ pip list | grep -E "neutron|generic-switch"
networking-generic-switch 4.0.1.dev3
neutron 17.2.1.dev4
neutron-dynamic-routing 17.0.1.dev3
neutron-fwaas 16.0.0
neutron-lib 2.6.1
