Segment Routing Traffic Engineering Policy (SR-TE) multi-agent routing model TOI

Description Segment Routing Traffic Engineering Policy (SR-TE) aka SR Policy makes use of Segment Routing (SR) to allow a headend to steer traffic along any path without maintaining per flow state in every node. A headend steers traffic into an “SR Policy”.    EOS 4.21.0F added support for SR Policy for the MPLS dataplane (SR-MPLS) for Type-1 SR Policy segments in single agent routing model. EOS 4.22.1F adds support for SR-TE in multi-agent routing model.    For a detailed description of the functional behavior please refer to the “Description” section of EOS 4.21.0F TOI for SR-TE in single agent routing...
