An LSP can be explicitly (statically) configured. Static LSPs are configured on every node along the path. The label’s forwarding information includes the address of the next hop router.
Use the following CLI syntax to configure a static LSP:
config>router>mpls
— static-lsp lsp-name
— to ip-address
— push out-label nexthop ip-addr
— no shutdown
The following displays a static LSP configuration example:
A:ALA-1>config>router>mpls# info
----------------------------------------------
...
static-lsp "static-LSP"
to 10.10.10.124
push 60 nexthop 10.10.42.3
no shutdown
exit
...
