4.1. BGP-Prefix Segment

A BGP-Prefix segment is a BGP segment attached to a BGP prefix.

A BGP-Prefix segment is global (unless explicitly advertised otherwise) within the SR domain.

The BGP-Prefix segment is the BGP equivalent to the IGP-Prefix segment.

A likely use case for the BGP-Prefix segment is an IGP-free hyper-scale spine-leaf topology where connectivity is learned solely via BGP [RFC7938]
