Usage guidelines

If the peer device does not support fragment reassembly, you must configure the ppp mp fragment

disable command to disable MP fragmentation on the local device. This enables the two devices to

communicate. After that, outgoing packets are not fragmented, but they still carry an MP sequence

number and fragment tag.

After you configure the ppp mp fragment disable command on an interface, the settings configured with

the ppp mp lfi enable and ppp mp min-fragment commands become invalid on the interface.

Examples

# Disable MP fragmentation on interface MP-group 1.

<Sysname> system-view

[Sysname] interface mp-group 1

[Sysname-MP-group1] ppp mp fragment disable
