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
