5. Configure LSP generation policies so LDP uses all static routes and IGP routes to establish LSPs:

# Configure Router S.

[RouterS] mpls ldp

[RouterS-ldp] lsp-trigger all

[RouterS-ldp] quit

# Configure Router D.

[RouterD] mpls ldp

[RouterD-ldp] lsp-trigger all

[RouterD-ldp] quit

# Configure Router A.

[RouterA] mpls ldp

[RouterA-ldp] lsp-trigger all

[RouterA-ldp] quit

Verifying the configuration

# Display LDP LSP information on routers, for example, on Router S. The output shows that primary and

backup LSPs have been established.
