Configuration saved by a software version with persistent CGAs
The file cfx:\system-pki\secureNdKey should exist. This file is automatically uploaded by SeND during initialization.
The configuration file should contain a modifier for each address on a SeND enabled interface.
Modifiers in the configuration file are checked against the current RSA key pair. If the check fails, a new modifier and CGA is generated and a warning is raised that a new CGA is generated.
If a modifier is missing from the configuration file for an IPv6 /64 prefix on a SeND enabled interface, a new modifier and CGA is generated based on the active RSA key pair.
Configuration saved by a software version having non-persistent CGAs
The file cfx:\system-pki\secureNdKey does not exist nor does the configuration file contain a modifier for any of the IPv6 /64 prefixes on secure-nd enabled interfaces.
New CGAs have to be generated (from the CLI context). Follow one of the procedures described in section Making non-persistent CGAs persistent to make the non-persistent CGA's persistent.
