name: CE name, unique in the current PE VPN.
id: CE ID, unique in VPN, represents a CE, ranging from 1 to 65535.
offset: Specifies default offset value of the original CE.
range: CE range, that is, the maximum number of CEs that the current CE can connect
to, ranging from 1 to 100. The default value is 10.
Description
Use the ce command to create a CE or modify the CE range.
Use the undo ce command to delete a CE.
After a CE is created, the system will create a CE mode and all the CE connections are
configured in this mode.
To facilitate VPN expansion, CE range can be configured larger than actual demand at
present. It is a waste of identifier however, because the identifier block distributed by
the system is as large as the CE range.
If the CE range is smaller than demand during VPN expansion, for example, the CE
range is 10 while the needed CE number is 20, you can modify the CE range to 20.
Related command: mpls l2vpn encapsulation and connection.
