R21xx-HP FlexFabric 11900 MPLS Command Reference

67
The local LSR and the peer LSR must have the same key. Otherwise, they cannot establish a TCP
connection.
After you change the MD5 authentication key, the local LSR uses the new key to re-establish an LDP
session with the specified peer.
Examples
# Enable LDP MD5 authentication for peer 3.3.3.3 in the public network, and set a plaintext key of pass.
<Sysname> system-view
[Sysname] mpls ldp
[Sysname-ldp] md5-authentication 3.3.3.3 plain pass

Usage guidelines
You must enable LDP globally for an LSR to run LDP.
The GR commands, the session protection command, and the targeted-peer command are available
only in LDP view. All other commands available in LDP view are also available in LDP-VPN instance view.
Commands executed in LDP view take effect only for the public network. Commands executed in
LDP-VPN instance view take effect only for the specified VPN instance. The GR commands are global
commands and take effect for all VPN instances and the public network.
Examples
# Enable LDP globally and enter LDP view.
