New SR-TE BW optimization tool.

(Tools > SR-TE BW Optimization)

The Segment Routing (SR) TE Bandwidth (BW) 
Optimization tool enables:

Reduction of the traffic utilization of selected 
interfaces to below a specified threshold.

Analysis on how well congestion mitigation 
works when using segment routing over 
different failure scenarios.

For more information, see the “SR-TE Bandwidth 
Optimization” chapter in the 

.

New LSP Disjoint Optimization tool.

(Tools > LSP Disjoint Path Optimization)

Extended support for LSP disjointness includes:

Enhancements to the disjointness algorithm 
that enable the optimization tools to find 
disjointness under a broader set of constraints.

Enhancements to Inter-Area for disjointness— 
the LSP Disjoint Path Optimization tool tries to 
find disjoint LSP paths for Inter-Area LSPs.

For more information, see the “LSP Disjoint Path 
Optimization” chapter in the

.

Enhancements to the LSP Loadshare 
Optimization tool.

(Tools > LSP Loadshare Optimization)

It is possible to specify a subset of interfaces whose 
utilization should be optimized. The produced 
reports are enhanced.

Enhancement to optimize inter-AS SR LSPs. See 
also the 

(Tools > SR-TE Optimization)

The SR-TE Optimization tool is extended to create 
Segment Lists for inter-AS SR LSPs.

For more information, see the “SR-TE 
Optimization” chapter in the 

.

Ability to set the number of new L1 circuits that 
are created when they are being duplicated.

For more information, see the “Simulation” chapter 
(“Duplicate L1 Objects”) in the 

Ability to set L1 node type.

For more information, see the “Layer 1 Simulation” 
chapter (“Create L1 Nodes”) in the 

Enhancement to find L1 links that are causing 
lambda blocking.

For more information, see the “Layer 1 Simulation” 
chapter (“Lambda Assignments”) in the 

.

Addition of a Network Option that controls 
whether Layer 1 rerouting has converged under 
failures.

The Simulation tab includes the new option: “Layer 
1 rerouting convergence under failures.”

Option to fail the L1 object causing the Worst 
Case L1 Utilization on a selected L1 Link.
