4.5.3 Creating CE and Configuring CE Connection

I. Creating CE
You need create on PE a CE which is consistent with the one physically connected to
PE and specify a unique ID for it. You can also specify the CE range.
Perform the following configurations in MPLS L2VPN view.

CE ID uniquely identifies a CE in a VPN, so it must be unique in a VPN. For the sake of
convenience, you are recommended to number the CE IDs from 1 and with
consecutive natural number.
CE range indicates how many other CEs a CE can be connected to at most. If label
resource is sufficient (which is often the case), you can set a CE range larger than the
actual needs taking in account the future VPN size. Then you can minimize the
modification in future if it is required to add CEs into the VPN in later expansion.
You have to modify the preset CE range if it is less than the needs in VPN expansion.
For example, if current CE range is 10, while 20 CEs are required in expansion, you
need to modify the value to 20. The existing ten links will not be cut off in modifying CE
range, since the system just applies for another block of 10 labels, instead of releasing
the existing label block and applying for another block of 20 labels.
