Learn about Bit Index Explicit Replication (BIER) technology in this 38-minute conference talk from NANOG81 by Distinguished Engineer Jeffrey Zhang from Juniper Networks. Dive deep into BIER as the optimal multicast solution for Segment Routing networks, building on concepts from the previous "Multicast Options in SR Networks" presentation. Explore how BIER technology is reaching deployment readiness with hardware support across multiple major vendors for access, edge, aggregation and core networks. Benefit from Zhang's 30+ years of routing technology expertise spanning OSPF/BGP/LDP/RSVP, MPLS-TE, MPLS/BGP-based services, Multicast (PIM/MVPN), VPLS/EVPN, RIFT, Segment Routing, and Mobile User Plane implementations.
