OpenStack SingleNode on existing Infrastructure
We currently have one server which isn't needed for anything else, so we wanted to install an openstack single node configuration to get some hands on time. Everything is finde except for the external network access.
The Server is on an untagged vlan 50 port on the switch. So my idea was to just create the external network as following:
neutron net-create --tenant-id <ID> -provider:network_type=vlan --provider:segmentation_id=1 --router:external=true EXT
neutron subnet-create --disable-dhcp --name ext_subnet EXT <NW> --gateway <GW>
After adding the router-gw:
neutron router-gateway-set gateway_router EXT
I can see in horizon that the router allocated an IP in the external network. But i am not able to ping the OpenStack Router IP from another server in the (same) external network.
Do i need to change the switch configuration, so the port on which the server is connected is a trunk and then change the provider:segmentation_id to 50? Or do i miss something completely?
Could i use vxlan and be completely independant from the switch?
