Title:
Network topology fail if router service is disabled
Status in OpenStack Dashboard (Horizon):
Invalid
Bug description:
In neutron, L3 service is disable.
In horizon, I disabled router features in local_setting
OPENSTACK_NEUTRON_NETWORK = {
'enable_distributed_router': False,
'enable_firewall': False,
'enable_ha_router': False,
'enable_lb': True,
'enable_quotas': True,
'enable_security_group': True,
'enable_vpn': False,
'profile_support': None,
'enable_router': False,
'enable_ipv6': False,
}
But network topology fail because neutron return 404 when horizon GET
on /v2.0/routers.json

NotFound: 404 Not Found
The resource could not be found.
Neutron logs :

I guess when 'enable_router': False, we need to disable router features in
network topology.
