The L2VPN EVPN address-family provides a versatile and converged networking solution that effectively addresses the design tradeoff of legacy Spanning Tree Protocol (STP)-enabled campus networks and transforms them into VXLAN-enabled fabric cores. The address-family functions of Multiprotocol BGP (MP-BGP) support diverse networking solutions for target networking use cases.

This chapter provides detailed step-by-step configuration to implement a two-tier hierarchical BGP peering by subdividing routing domains between EVPN multihoming and fabric core to support scalability and resiliency.
