An LSP can be explicitly (manually) configured. The reserved range of static LSP labels is 32 to 1023. Static LSPs are configured on every node along the LSP 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
label
nexthop
ip-address
no shutdown
config>router# mpls
config>router>mpls# static-lsp
static-LSP
config>router>mpls>static-lsp$ to
10.10.10.124
config>router>mpls>static-lsp# push
60
nexthop
10.10.42.3
config>router>mpls>static-lsp#
no shutdown
config>router>mpls>static-lsp# exit
The following example displays the static LSP configuration output.
