Configuring 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.

You can configure one of the following statements (you can only configure one of these statements at a time) to alter the behavior of CSPF tie-breaking:

To configure a random tie-breaking rule for CSPF to use to choose among equal-cost paths, include the random statement:random;
To prefer the path with the least-utilized links, include the least-fill statement:least-fill;
To prefer the path with the most-utilized links, include the most-fill statement:most-fill;

You can include each of these statements at the following hierarchy levels:

[edit protocols mpls label-switched-path lsp-name]
[edit logical-systems logical-system-name protocols mpls label-switched-path lsp-name]
