What to Do Next
The following example of the show ppp multilink command shows the MLPPP type and the fragmentation
size:

Disabling Fragmentation on an MLPPP Bundle
By default, PPP multilink fragmentation is enabled. To disable fragmentation on a multilink bundle, use the
following commands:
SUMMARY STEPS
1.
Router# configure terminal
2.
Router(config)# interface multilink group-number
3.
Router(config-if)# ppp multilink fragment disable
DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.Router# configure terminal
Step 1
Specifies the multilink interface and enters multilink interface
mode, where:
Router(config)# interface multilink
group-number
Step 2
•
group-number—The group number for the multilink
bundle. Range 1-2147483647
Disables PPP multilink fragmentation.Router(config-if)# ppp multilink fragment
disable
Step 3
Configuring LFI
Link Fragmentation and Interleaving (LFI) is implemented on the QFP on the Cisco ASR 1000 Series
Aggregation Services Routers. QFP-based LFI supports LFI on a bundle with any number of links—from one
link, up to the maximum number supported by the router. When using LFI on MLPPP, the QFP load balances
the priority packets across all links in the bundle to minimize the latency on the priority interleaved traffic.
