Configuring an LSP

The next step in configuring signaled LSPs is to create one or more LSPs and define the properties associated with the label-switched path on the ingress router. To configure an LSP, include the label-switched-path statement:




label-switched-path lsp-name {

disable;

adaptive;

admin-down;



admin-group {

exclude [ group-names ];

include-all [ group-names ];

include-any [ group-names ];
}





auto-bandwidth {

adjust-interval seconds;

adjust-threshold percent;

maximum-bandwidth bps;

minimum-bandwidth bps;

monitor-bandwidth;
}





bandwidth bps {
ct0 bps;
ct1 bps;
ct2 bps;
ct3 bps;
}



class-of-service cos-value; 

description text;



fast-reroute {
(bandwidth bps | bandwidth-percent percent);
(exclude [ group-names ] | no-exclude);

hop-limit number;
(include-all [ group-names ] | no-include-all);
(include-any [ group-names ] | no-include-any);
}



from address; 

hop-limit number; 



install {

}



ldp-tunneling;

}

}


}

You can include this statement at the following hierarchy levels:

[edit protocols mpls]
[edit logical-systems logical-system-name protocols mpls]

Each LSP must have a name, lsp-name, which can be up to 32 characters long and can contain letters, digits, periods (.), and hyphens (-). The name must be unique within the ingress router. For ease of management and identification, configure unique names across the entire domain.

When you configure LSPs, you can specify the following statements either for each LSP or for each path. For statements that you configure on a per-LSP basis, the value applies to all paths in the LSP. For statements that you configure on a per-path basis, the path value overrides the per-LSP value.

For maintenance purposes, you can also configure the following attributes across all LSPs and any paths within those LSPs:

For each LSP, you can configure the following properties:
