2.5 Configuring LDP LSPs

LDP can distribute labels to establish LSPs in an MPLS domain.

2.5.1 Establishing the Configuration Task

Before configuring LDP LSPs, familiarize yourself with the applicable environment, complete
the pre-configuration tasks, and obtain the data required for the configuration.
Applicable Environment
LDP is used to distribute labels on an MPLS network and establish LSPs automatically in the
situation where paths for the LSPs do not need to be specified and traffic engineering (TE) does
not need to be deployed on the MPLS network.
The number of LSPs that an LSR supports depends on the capacity and performance of the LSR.
A large number of LSPs probably lead to unstable LSR operation.
LSPs can be established based on eligible routes and a policy for triggering LSP establishment.
The LSP establishment policy filters out unqualified routes and allows LDP to use eligible routes
to establish LSPs and control the number of LSPs.
Policies for triggering the LSP establishment are used based on the following types of LSPs:

: 3.3.3.9
Ingress or egress LSPs can be established based on the following policies:
– All static routes and IGP routes trigger LSP establishment.
– Labeled public network BGP routes to destination addresses with 32-bit masks trigger
LSP establishment. For the configuration procedure, see the chapter "BGP/MPLS IP
