l Set the MTU of the L2VPN on the PE to be the same as the MTU on the other equipment.
l Do not check the MTU.
Step 5 (Optional) Run:
ignore-mtu-match
The MTU value is not checked.
Step 6 Run:
vpn-target vpn-target &<1-16> [ both | export-extcommunity | import-extcommunity ]
The VPN target is configured.
To configure a Kompella VLL, you must create an MPLS L2VPN instance on the PE for each
directly connected CE.
When an L2VPN is created, the encapsulation type must be consistent with the encapsulation
type on the CE interface.
The usage of VPN target and RD is the same as the usage of those on the BGP/MPLS IP VPN.
For a Kompella VLL, you must configure RD. In addition, the RD cannot be modified after
configuration. The only way to modify RD is to delete the existing VLL and create a new one.

4.6.5 Creating a CE Connection
Context
Do as follows on the PEs on the two ends of the VC.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
mpls l2vpn vpn-name
The MPLS L2VPN view is displayed.
Step 3 Run:
ce ce-name id ce-id [ range ce-range ] [ default-offset ce-offset ]
The CE is created and the MPLS L2VPN CE view is displayed.
Step 4 Run:
connection [ ce-offset id ] interface interface-type interface-number [ tunnel-
policy policy-name ] [ raw | tagged ]
A CE connection is created.
NOTE
All Kompella L2VPN instances and VPLS VSI instances of a device share one label block; therefore, the
sum of the ranges of all Kompella L2VPN instances and VPLS VSI instances cannot exceed the size of
the label block. If the size exceeds the limit, the system prompts that the labels cannot be obtained because
the required labels exceed the upper limit; thus, allocation of a site ID to a VSI or creation of a CE fails.
