Configure CSPF Tie-Breaking

When selecting a path for an LSP, CSPF uses a tie-breaking process if there are several equal-cost paths. For information about how CSPF selects a path, see How CSPF Selects a Path. To configure a random tie-breaking rule for CSPF to use to choose among equal-cost paths, include the random statement at the [edit protocols mpls path label-switched-path lsp-path-name ] hierarchy level:

[edit protocols mpls path label-switched-path lsp-path-name ] 

random; 

To prefer the path with the least-utilized links, include the least-fill statement at the [edit protocols mpls path label-switched-path lsp-path-name ] hierarchy level:

[edit protocols mpls path label-switched-path lsp-path-name ] 

least-fill; 

To prefer the path with the most-utilized links, include the most-fill statement at the [edit protocols mpls path label-switched-path lsp-path-name ] hierarchy level:

[edit protocols mpls path label-switched-path lsp-path-name ] 

most-fill;
