Configuring Fragmentation on Multiclass MLPPP Interfaces

You can configure fragmentation on a multiclass MLPPP interface with the same fragment size as that of the MLPPP interface.

Before you configure fragmentation on the multiclass MLPPP interface:

• Ensure that fragmentation is enabled on the MLPPP interface.

  See Configuring MLPPP Fragmentation and Reassembly in Chapter 8, Configuring Multilink PPP.

To configure fragmentation on a multiclass MLPPP interface:

• Specify the QoS traffic classes to be fragmented.

  • To configure fragmentation on multilink classes in a dynamic profile:

    host1(config-profile)#ppp multilink multiclass fragmentation best-effort voice otherData video

  • To configure fragmentation on multilink classes in a static MLPPP interface:

    host1(config-if)#ppp multilink multiclass fragmentation best-effort voice otherData video

  The order of the QoS traffic classes does not affect the execution of the command.

  Note: You must include the best-effort traffic class in the ppp multilink multiclass fragmentation command, or the command fails.
