Understanding SR-MPLS and SRv6 Policies
This section details the SR-MPLS and SRv6 policy features available in Cisco Crosswork. It covers viewing policies on the topology map, understanding policy details, and visualizing IGP paths and metrics.
Key functionalities include:
- Visualizing SR-MPLS and SRv6 policies on the topology map.
- Viewing detailed SR-MPLS and SRv6 policy information.
- Visualizing IGP paths and associated metrics.
- Identifying Multiple Candidate Paths (MCPs).
- Understanding underlying paths for Binding-Segment ID (B-SID) labels.
- Visualizing native SR paths.
For a comprehensive list of limitations and important notes, refer to the Cisco Crosswork Network Controller Release Notes.
Configuring TE Link Affinities
Learn how to configure TE link affinities within the Crosswork Network Controller. This feature allows for consistent affinity mapping across SR policies, Tree-SIDs, and RSVP-TE tunnels.
Affinity configuration involves defining names and bit positions, which can represent various link attributes like low delay or high bandwidth, simplifying reference to these attributes.
Policy Deployment and Management
This document guides users through the process of deploying and managing SR-MPLS policies.
Key procedures include:
- Creating explicit SR-MPLS policies using a list of prefix or adjacency Segment IDs.
- Creating dynamic SR-MPLS policies based on optimization intent, allowing the SR-PCE to automatically re-optimize paths.
- Creating SR-TE policies initiated by the PCC (Path Computation Client).
- Modifying and deleting existing SR-MPLS policies.
Considerations for policy deployment, such as timeouts in scaled environments, are also discussed.
