id: CE ID, which is used to uniquely identify a CE in the VPN. This argument ranges 
from 0 to 499.

offset: Specifies the default original CE offset.

range: CE Range, the maximum number of CEs that can be connected to the CE. 
This argument ranges from 1 to 500.

Use the ce command to create a CE or modify the CE Range.

Use the undo ce command to remove a CE.

The corresponding CE view is created when you create a CE. All the CE 
connections are configured in CE view.

For VPN capacity expansion, you can set the range argument to a value lager than 
the currently required number of CEs to be connected. However, this may result in 
the waste of tags as the system allocates tag blocks for CEs according to the value 
of the range argument. You can also change the CE Range to a larger number 
when expanding the VPN (if the previously set CE range is not large enough). For 
example, if the desired CE number is 20 after the expansion, but the current CE 
Range is 10, you can change the CE range to 20.
