MPLS Label Distribution Protocol (LDP)
Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) enables peer label switch
routers (LSRs) in an MPLS network to exchange label binding information for supporting hop-by-hop
forwarding in an MPLS network. This module explains the concepts related to MPLS LDP and describes
how to configure MPLS LDP in a network.

History for the MPLS LDP Feature
Release
Modification
12.0(10)ST
This feature was introduced in 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 reflected MPLS command syntax and
terminology, thus facilitating the orderly transition from a network using
the Tag Distribution Protocol (TDP) to one using the Label Distribution
Protocol (LDP).

12.0(14)ST
This feature was integrated into Cisco IOS Release 12.0(14)ST. This
release introduced several new MPLS CLI commands, provided support
for MPLS VPNs by means of a new vrf vpn-name parameter in certain
existing commands, and modified other commands to ensure consistent
interpretation of associated prefix-access-list arguments by Cisco IOS
software.

12.2(4)T
This feature was integrated into Cisco IOS Release 12.2(4)T. Also, support
was added for Cisco MGX 8850 and MGX 8950 switches equipped with a
Cisco MGX RPM-PR card, and the VPI range in the show mpls atm-ldp
bindings and show mpls ip binding commands was changed to 4095.
