Configuring MPLS Paths

When configuring an MPLS path for LSPs, the IP address of each hop 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 other routers (loose).

Use the following CLI syntax to configure a path:

CLI Syntax:

config>router>mpls
    path path-name
        hop hop-index ip-address {strict|loose}
        no shutdown

The following example displays a path configuration output.

A:ALU-1>config>router>mpls# info
------------------------------------------
            interface "system"
            exit
            path "to-NYC"
                hop 1 10.10.10.103 strict
                hop 2 10.10.0.210 strict
                hop 3 10.10.0.215 loose
            exit
            path "secondary-path"
                hop 1 10.10.0.121 strict
                hop 2 10.10.0.145 strict
                hop 3 10.10.0.1 strict
                no shutdown
            exit
