The ‘bigip_add’ command pulls the management certificate from the destination BIGIP devices for use during the encrypted iQuery channel setup between GSLB servers in the cluster. When running ‘bigip_add’ without any options, the command will be run against all BIGIP devices in the GSLB Server list using current username to connect to the endpoints. You can specifiy a connection username or endpoint IP(s) if needed.
