• ce-offset ce-id: Specifies the ID of the peer CE that establishes a local or remote connection with the
local CE.
If you execute the connection command without specifying the ce-offset ce-id option:
{ When you first execute the connection command, the PE creates a connection between the local
CE and the peer CE with an ID of default-offset. If the default-offset equals the local CE ID, the
PE creates a connection for the local CE and the peer CE with an ID of default-offset+1.
{ When you execute the connection command for the second time, the PE creates a connection
between the local CE and the peer CE with an ID of "previous connection CE ID+1." If the
"previous connection CE ID+1" equals the local CE ID, the PE creates a connection for the local
CE and the peer CE with an ID of "previous connection CE ID+2."
When you plan a VPN, HP recommends that you set CE IDs in incremental sequence and then
configure CE connections in the sequence of CE IDs so you can omit the ce-offset keyword (use the
default setting) for most connections.
• To modify the CE range by executing the ce command, you can only change the CE range to a
bigger value than that of the current CE range. For example, if the current CE range is 10, you can
change it to 20, but you cannot change it to 5. Changing the CE range to a bigger value does not
interrupt current services. To change the CE range to a smaller value, you must delete the current CE,
re-create the CE, and specify a smaller CE range for it.

Command Remarks
1. Enter system view.
system-view N/A
2. Enter MPLS L2VPN view.
mpls l2vpn vpn-name N/A
3. Create a CE, specify the CE
name, CE ID, CE range, and
the initial CE ID, and enter
MPLS L2VPN CE view.
ce ce-name [ id ce-id [ range
ce-range ] [ default-offset
default-offset ] ]
N/A
4. Create a Kompella
connection.
connection [ ce-offset ce-id ]
interface interface-type
interface-number [ tunnel-policy
tunnel-policy-name ]
The ce-offset ce-id option
determines whether the connection
is a local connection or a remote
connection. If the specified CE is
connected to the same PE as the
local CE, the connection is a local
connection. Otherwise, the
connection is a remote connection.
The interface interface-type
interface-number option specifies a
PE-CE interface of the PE. By
specifying the interface, you bind
the AC link on the interface to the
Kompella connection.
