Overview
Introduces BGP labeled unicast solutions, MPLS support, label allocation methods, per-VRF options, traffic steering, and related configurations to optimize and scale MPLS networks with label management and advanced convergence features.
This chapter provides comprehensive guidance on BGP labeled unicast (BGP LU) features, enabling scalable MPLS transport across diverse network topologies, including multi-area and multi-AS environments. It details various BGP LU implementations like RSVP-TE, IPv6, MPLS IP POP, and fast convergence with PIC edge. You will also learn how to optimize label allocation and steer BGP control-plane traffic over IP-only paths for enhanced network efficiency.
