Cisco Cisco IOS Software Release 12.0(13)S7

The MPLS—LDP MD5 Global Configuration feature provides enhancements to the Label Distribution 
Protocol (LDP) implementation of the Message Digest 5 (MD5) password. This feature allows you to 
enable LDP MD5 globally instead of on a per-peer basis. Using this feature you can set up password 
requirements for a set of LDP neighbors to help prevent unauthorized peers from establishing LDP 
sessions and to block spoofed TCP messages.

This document provides information about and configuration information for the global configuration of 
LDP MD5 protection.
