Note that you can only increase the CE range. For example, if the original CE range is 10, you can
increase it to 20, but cannot reduce it to 5. The only way to reduce the CE range is to delete the CE
and re-create it.
When you increase the CE range, for example, from 10 to 20, the system does not release the original
label block and then re-apply for a new label block of the size of 20. Instead, the system applies for a
supplementary label block of the size of 10. This ensures that the existing services will not be
interrupted.
