Outlines SR LSP optimization tools that minimize metrics and hops for SR LSPs and set routes based on traffic engineering, alongside bandwidth optimization for congestion mitigation and post-failure reoptimization.
The SR-TE optimization is a Cisco Crosswork Planning tool
-
creates or updates segment lists to minimize the sum total of user-specified metrics for selected SR LSPs, including inter-AS LSPs, using the fewest number of segment list hops as possible
-
sets the routes based on traffic engineering criteria, and
-
optimizes a sequence of node or adjacency hops for the SR LSP paths to follow.
The SR-TE bandwidth optimization tool lets you reduce the traffic utilization of selected interfaces to below a specified threshold. This ability to mitigate congestion is useful when planning for increased traffic and when determining if service-level agreements can be met in the event of congestion. Additionally, you can use this tool for reoptimizing bandwidth after events, such as network failures and subsequent route reconvergence.
