Optimization output

Lists and describes the generated optimization output by the optimization tool.


The RSVP-TE optimization tool produces several key outputs, including specific properties, detailed reports, and updated LSP configurations designed to maximize network efficiency.

Properties created

In addition to creating the input parameters as described in Table 1, the tool generates the properties listed in Table 1. These properties provide insights into the optimizations.

Property

Description

LSPs

RSVPTEOpt::Action

Identifies whether the LSP’s path was updated (optimized).

RSVPTEOpt::PathMetric

Sum of interface metrics on the LSP path.

RSVPTEOpt::ShortestPath

Identifies whether the LSP is now taking the shortest path.

RSVPTEOpt::ShortestPathMetric

Sum of interface metrics on the shortest LSP path.

Interfaces

RSVPTEOpt::BWTotal

Sum of the bandwidth required for all LSPs routed on the interface.

RSVPTEOpt::BWBoundExceeded

Identifies whether the bandwidth bound of the interface was exceeded.

Reports

Each time the optimizer is run, a report is automatically generated. You can access this information by choosing Actions > Reports > Generated reports. Note that new reports replace any previously generated reports.

The report summarizes the optimization results, including:

  • The total number of LSPs and how many were optimized

  • How the optimizations were performed

  • Handling of disjoint priorities

  • The number of paths that exceeded the interface’s bandwidth limit

Reconfigured optimized LSPs

The optimized LSPs are reconfigured with these parameters:

  • Metric type: Autoroute

  • Metric and Hop limit: NA

  • Setup BW: 0, the same value as the resulting RSVPTEOpt::BWReq, or unchanged, depending on how you configured the Post Optimization option in the Advanced tab.

  • Primary paths Standby: T (true)

  • Status: Active

  • FRR enabled: T (true)

  • LSP entry in the Actual paths table is removed.
