PPP Notes – LFI

  • Link Fragmentation and Interleaving
  • A QoS tool to prevent smaller, higher-priority packets from waiting on larger packets to transmit
    • For example, VoIP packets and FTP packets
  • Fragments the larger packets and interleaves them with the smaller packets
  • Only available in PPP with Multilink
    • Can be a multilink bundle with a single link in it
  • Common to use with LLQ to interleave the delay-sensitive packets
  • fragment-delay allows you to change the fragment size
    • In milliseconds
    • size = fragment-delay * bandwidth of interface


Corrections, please.

I shake my head around sometimes and see what falls out. That's what lands on these pages.
