After completing the above configurations, you will find by issuing the following commands on Switch A
that the remote LDP session with Switch C is already established:

Example for Configuring LDP to Establish LSPs
Network requirements
On the network in Figure 1-10 , an LSP is required between Switch A and Switch C. Check the validity
and reachability of the LSP.
Configuration procedure
1) Configure LDP sessions. Refer to Example for Configuring LDP Sessions .
2) Configure the LSP establishment triggering policy for LDP to establish LSPs.
For LDP to establish an LSP, LDP sessions are required between neighboring routers along the LSP. In
Figure 1-10 , an LDP LSP can be established from Switch A to Switch C provided that local LDP
sessions exist between Switch A and Switch B, and between Switch B and Switch C; no remote LDP
session is required between Switch A and Switch C.
# Configure Switch A.
[SwitchA] mpls
[SwitchA-mpls] lsp-trigger all
[SwitchA-mpls] return
# Configure Switch B.
