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 for 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
for 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, H3C recommends that you set CE IDs in incremental sequence and then
configure connections in the sequence of the CE IDs, in which case you can omit the
ce-offset
keyword (use the default setting) for most of the connections.
•
To modify the CE range by re-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.
