Floating tunnels with names more than 15 characters may cause issues in config-sync, because such a long name is truncated when creating a corresponding Linux tunnel interface.
When the config-sync happens, the following error may occur: Caught configuration exception (0), Cannot create tunnel 'g123456789abc~1' in rd0 - ioctl failed: File exists.
The BIG-IP system consists of both floating and non-floating tunnels and their names are longer than 15 characters.
Some workarounds are available: - Make sure that tunnel names are less than 16 characters; or - Make sure that the names of floating and non-floating tunnels do not share a common prefix in the first 15 characters; or - Make sure that the BIG-IP system does not have a mixture of floating and non-floating tunnels.
