• After you configure the undo ppp mp fragment enable command on an interface, the settings
configured with the ppp mp lfi and ppp mp min-fragment commands become invalid on the
interface.

Configuring short sequence number header format negotiation
By default, an MP bundle receives and transmits fragments with long sequence numbers.
• 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.
The sequence number format (long or short) of an MP bundle depends on the configuration of the first
channel joining the MP bundle.
