Networking¶
Networks¶
With the exception of the manager, all nodes have a connection to any network. The manager only has no connection to the storage backend.
Name |
CIDR |
Description |
---|---|---|
management |
|
SSH access via this network & all internal communication |
wireguard |
|
Is used by Wireguard. |
provider |
|
Is used to emulate an provider network. |
Warning: The provider network is set up with VXLAN tunneling between the nodes and can currently only be used when OVN is being used as Neutron backend (this is the default). Trying to switch to OVS will cause a conflict, since OVS will also try to use VXLAN as tunnel mechanism. See https://github.com/osism/testbed/issues/1065 for details.
Nodes¶
The nodes always have the same postfix in the networks.

Without these entries e.g. the VNC access to instances does not work.
