•
If the local end wants to receive fragments with short sequence numbers, it should request the peer
to transmit short sequence numbers during LCP negotiation. After the negotiation succeeds, the
peer transmits fragments with short sequence numbers.
•
If the local end wants to transmit fragments with short sequence numbers, it should ask the peer to
send a request for receiving short sequence numbers during LCP negotiation. After the negotiation
succeeds, the local end transmits fragments with short sequence numbers.
To configure short sequence number header format negotiation for MP:
Step Command

1.
Enter system view.

2.
Enter interface view.

N/A
3.
Trigger MP short sequence
number header negotiation,
specifying that the interface
receive fragments with short
sequence numbers after the
negotiation succeeds.
ppp mp short-sequence
By default, long sequence number
header format negotiation is
performed.
NOTE:
•
The sequence number format (long or short) of an MP bundle depends on the configuration of the first
channel joining the MP bundle.
•
To negotiate the use of short sequence numbers, use the command on all its channels. Note that the
command will cause PPP re-negotiation.
Configuring MP endpoint options
During the LCP negotiation for MP, endpoint options are negotiated for bundling.
By default, the endpoint option in the packets sent out an interface is the router name. After you use the
ppp mp mp-group command to add the interface to the specified MP-group interface, the endpoint
option in the packets sent out the interface is the MP-group interface name. As the endpoint option is of
up to 20 bytes, if the default is of more than 20 bytes, the first 20 bytes are taken as the endpoint option.
You can use the following commands to configure the endpoint option in the packets sent out an
interface.
To configure the MP endpoint option:
