nice talking to you on the phone.
As mentioned, as a framework we need to be able to work with the/all different possibilities. Since the management VRF is not mandatory to use, the CMDB nodes won’t use this. This doesn’t have any impact on the SSH session. It will impact the (pre/post) backups if the mgmt IP is in another VRF than ‘default’.
If the nodes are modeled as YCE nodes, the VRF can be linked to the node, where the flag “VRF management” can be enabled. This will alter the backup commands to use the VRF for which management is enabled. This allows you to use other VRF for management than ‘management’ itself as well. This isn’t limited to the Nexus family either.
If you just wish to communicate with the nodes, without the backups, you may disable those in the state_actions table, under Admin > Custom Data. Please use the following screenshot to accomplish this. (mind the search filters)
