Configuring short sequence number header format negotiation

By default, an MP bundle receives and transmits fragments with long 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.

To negotiate the use of short sequence numbers on a dialer MP bundle, configure the command on the dialer interfaces and the ISDN D channels. To negotiate the use of short sequence numbers on a common MP bundle, use the command on all its channels. Note that the command will cause PPP re-negotiation.

To configure short sequence number header format negotiation for MP:
