Step 3 Run:
undo ppp mp reorder-window
The command disables the regrouping of the fragments of the MP packets.
By default, the regroup of the fragments of the MP packets is enabled.
To improve the forwarding performance of the small packet, you can run the undo ppp mp
reorder-window command on the MP-Group interface to disable the re-group of the MP
fragments.

NOTE
After this command is run:
• To perform the MP binding through the Virtual-Template, you need to restart all the bundled links.
• To perform the MP binding through the MP-Group, you need to restart the MP-Group interface or all
the bundled links.
This command can guarantee the fragment order of the packets. To guarantee the received
packets on the MP group interface and the packet fragments to be consistent with those during
the sending, you can run the ppp mp reorder command for Configuring the packet order
guarantee function on the MP-group interface.
After the packet order guarantee function is configured on the MP-Group interface, the ppp
mp reorder-window command is invalid automatically.

6.10.4 Configuring the packet order guarantee function on the
MP-group interface
CQ NOTE
You can configure this function on the low-speed MP-Group interface and cannot be configured on the
high-speed MP-group interface.
A
The packet order guarantee function on the MP-Group interface can guarantee that the
receiving order and sending order of the MP packets are consistent. However, in the case that
the packets are lost or the bandwidth of the sub-channels differs greatly, the order of certain
packets cannot be guaranteed. You make the bandwidth of the bundled links similar in one
MP-group.
Do as follows on the routers:
Step 1 Run:
system-view
The system view appears.
Step 2 Run:
