Cisco IOS Release 12.0(10)ST,
incorporating a new set of
Multiprotocol Label Switching
(MPLS) CLI commands
implemented for use with Cisco
routers and switches. The CLI
commands in this release

and terminology, thus facilitating
the orderly transition from a
network using the Tag
Distribution Protocol (TDP) to
one using the Label Distribution
Protocol (LDP).
In Cisco IOS Release 12.0(14)ST,
several new MPLS CLI
commands were introduced,
support for MPLS VPNs was
added by means of a new vrf vpn-
nameparameter in certain existing
commands, and other commands
were modified to ensure
consistent interpretation of
associated prefix-access-list
arguments by Cisco IOS
software.
In Cisco IOS 12.1(2)T, this
feature was integrated into this
release. Also, the debug mpls
atm-ldp api, debug mpls atm-
ldp routes,and debug mpls atm-
ldp statescommandswere
