Refer to the exhibit.

You must complete the configuration on R1 so that a maximum of three links can be used and fragmentation is supported.
Which additional configuration accomplishes this task?
Correct Answer: A
Explanation/Reference:
Explanation:
The "ppp multilink interleave" command is needed to enable link fragmentation and Interleaving (LFI). The Cisco IOS Link Fragmentation and Interleaving (LFI) feature uses Multilink PPP (MLP). MLP provides a method of splitting, recombining, and sequencing datagrams across multiple logical data links. MLP allows packets to be fragmented and the fragments to be sent at the same time over multiple point-to-point links to the same remote address.
ppp multilink links maximum
To limit the maximum number of links that Multilink PPP (MLP) can dial for dynamic allocation, use the ppp multilink links maximum command in interface configuration mode. ReferencE. http://www.cisco.com/c/en/ us/td/docs/ios/12_2/qos/configuration/guide/fqos_c/qcflfi.html
