Configuring Remote LDP Session Parameters
LDP sessions established between remote LDP peers are referred to as remote LDP sessions.
Remote LDP sessions are mainly used in Martini MPLS L2VPN and Martini VPLS. See MPLS L2VPN
Configuration and VPLS Configuration in the MPLS Configuration Guide for details.
To establish a remote LDP session:
z
Determine the LDP transport addresses of the two peers and make sure that the LDP transport
addresses are reachable to each other. This is to establish the TCP connection.
z
If there are a many LDP sessions between the two LSRs or the CPU is occupied much, you need
to adjust timers to ensure the stability of the LDP sessions.
Follow these steps to configure remote LDP session parameters:
