L2TP See Layer Two Tunneling Protocol (L2TP).
LAN See local area network (LAN).
LAN requester See requester (LAN requester).
Last Known Good configuration A hardware configuration that is available by

the configuration information saved after the last successful logon.
LAT See local area transport (LAT).
layering The coordination of various protocols in a specific architecture that allows
the protocols to work together to ensure that the data is prepared, transferred,

Layer Two Tunneling Protocol (L2TP) Its primary purpose is to create an
encrypted tunnel through an untrusted network. L2TP is similar to Point-to-Point
Tunneling Protocol (PPTP) in that it provides tunneling but not encryption. L2TP
provides a secure tunnel by cooperating with other encryption technologies such
as IPSec. L2TP functions with IPSec to provide a secure virtual private network
solution.
