Configure an LSP path to use in MPLS. When configuring an LSP, the IP address of the hops that the LSP should traverse on its way to the egress router must be specified. The intermediate hops must be configured as either strict or loose meaning that the LSP must take either a direct path from the previous hop router to this router (strict) or can traverse through other routers (loose).
Use the following syntax to configure a path.
config>router> mpls
path path-name
hop hop-index ip-address {strict|loose}
no shutdown

hop 1 10.10.0.121 strict
hop 2 10.10.0.145 strict
hop 3 10.10.0.1 strict

path "to-NYC"
hop 1 10.10.10.103 strict
hop 2 10.10.0.210 strict
hop 3 10.10.0.215 loose
