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.
• 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.
