Description
Using the ce command, you can create CE or modify CE range. Using the undo ce
command, you can delete CE.
After CE is created, system will create a CE mode and all the configurations of CE
will be performed in this mode.
To facilitate VPN expansion, CE range can be configured larger than the real
capacity. But it’s a waste of identifier because system will distribute an identifier
block as large as the CE range.
If the CE range is smaller than need in VPN expansion, for example, the CE range
is 10 while the needed CE number is 20, you can modify the CE range to 20.
For the related command, see mpls l2vpn encapsulation, connection.
Example
Create a CE for vpna, named “Marlborough,” with CEID being 1, range default
value being 10.
