Resetting L2Vpn Bgp Sessions - HP HSR6800 Configuration Manual

•
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."
As a best practice to plan a VPN, 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.
Configuration procedure
To create a CE connection:
Step
1. Enter system view.
2. Enter MPLS L2VPN view.
3. Create a CE, specify the CE
name, CE ID, CE range, and
the initial CE ID, and enter
MPLS L2VPN CE view.
4. Create a Kompella
connection.

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.
