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

R1(config)#interface Multilink 1
R1(config-if)#bandwidth 512
R1(config-if)#ppp multilink interleave
R1(config-if)#ppp multilink delay 10

Aaron does lots of stuff and, therefore, does nothing well. He's trying, though.
