R3303-HP HSR6800 Routers Layer 2 - WAN Configuration Guide

44
• When MP binding is based on authentication username only, peer devices cannot be differentiated.
If an MP bundle involves multiple devices, set the binding mode to both.
• For a VT interface, if a static route is used, specify the next hop rather than the outgoing interface.
If the outgoing interface must be specified, make sure that the physical interfaces bound to the VT
are active to ensure normal transport of packets.
To configure other optional parameters:

Command Remarks
1. Enter system view.
system-view N/A
2. Create an MP VT interface
and enter its view.
interface { virtual-template }
number
N/A
3. Set the binding mode.
ppp mp binding-mode
{ authentication | both |
descriptor }
Optional.
By default, MP binding is based on
both the PPP authentication
username and the descriptor.
4. Set the maximum number of
links allowed in an MP
bundle.
ppp mp max-bind max-bind-num
Optional.
16 by default.
This command is available in VT
interface view and dialer interface
view.
Changing the number might
impact the PPP performance. In
most cases, the change is not
necessary. If you have to change
the number, do so under the
guidance of the technical
engineer.
5. Set the minimum number of
links required in an MP
bundle.
ppp mp min-bind min-bind-num
Optional.
This command is available only in
dialer interface view.
By default, the minimum number of
links in an MP bundle is 0, that is,
MP dialup depends on traffic
detection.
6. Enable MP fragmentation.
ppp mp fragment enable
Optional.
Enabled by default.
7. Set the minimum size of MP
fragments.
ppp mp min-fragment size
Optional.
128 bytes by default.
Configuring MP through an MP-group interface
When you configure MP through an MP-group interface, follow these guidelines:
• The ppp mp max-bind command and the ppp mp min-fragment command you configured can take
effect on an MP bundle only after you re-enable all the physical interfaces in the MP bundle by
executing the shutdown command and then the undo shutdown command.
