Requirements •

Requirements: management LXC

•

Does not depend on having used ANK for routing protocols

•

just that the devices are accessible via LXC to mgmt ip

•

use infra only mode in ANK to setup basic •

•

see YouTube on Manual Configurations

or add config stanza manually for launch to inject
