Defaults If fragmentation is enabled, the fragment delay is 30 milliseconds.
Usage Guidelines
The ppp multilink fragment-delay command is useful when packets are interleaved and traffic
characteristics such as delay, jitter, and load balancing must be tightly controlled.
MLP chooses a fragment size on the basis of the maximum delay allowed. If real-time traffic requires a
certain maximum boundary on delay, using the ppp multilink fragment-delay command to set that
maximum time can ensure that a real-time packet gets interleaved within the fragments of a large packet.
By default, MLP has no fragment size constraint, but the maximum number of fragments is constrained
by the number of links. If interleaving is enabled, or if a fragment delay is explicitly configured with the
ppp multilink fragment-delay command, then MLP uses a different fragmentation algorithm. In this
mode, the number of fragments is unconstrained, but the size of each fragment is limited to the
fragment-delay value, or 30 milliseconds if the fragment delay has not been configured.
The ppp multilink fragment-delay command is configured under the multilink interface. The value
assigned to the delay-max argument is scaled by the speed at which a link can convert the time value into
a byte value.

ppp multilink interleave Command

To enable interleaving of real-time packets among the fragments of larger nonreal-time packets on a
MLP bundle, use the ppp multilink interleave command in interface configuration mode. To disable
interleaving, use the no form of the command.

Defaults Interleaving is disabled.
Usage Guidelines The ppp multilink interleave command applies to multilink interfaces, which are used to configure a
bundle.
Interleaving works only when the queuing mode on the bundle is set to fair queuing.
