This feature adds support for BGP UCMP in the multi agent routing protocol model. The TOI for BGP UCMP in the ribd

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.

This feature extends link bandwidth extended community deletion mechanism, which previously always required

Unequal cost multi path (UCMP) for BGP is a mechanism for forwarding ECMP route traffic using weights, with which the
