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
