The first quarter of the book focuses on VXLAN fabric's Underlay Network. It starts by explaining the operation of OSPF, the Dijkstra algorithm, and the Shortest Path Tree calculation process. Then it discusses the differences between the OSPF and IS-IS routing protocols from the Underlay Network perspective. The first part also introduces Underlay Network routing solutions with Single-AS solution, Dual-AS solution, and Multi-AS solution. After the Unicast Routing section, this book explains the Multicast Routing solution used for L2VNI specific L2BUM traffic forwarding by introducing the Anycast-RP with PIM and the PIM BiDir solutions. The focus of the second quarter is VXLAN with BGP EVPN Control Plane. It explains the basic building blocks and configurations needed for both Layer2 and Layer3 services. It also discusses the BGP EVPN Control Plane operation by showing how a BGP EVPN NLRI information is advertised within a VXLAN fabric and how information is used in Data Plane. The third quarter discusses a multi-homing solution with vPC by explaining the vPC Multi-homing, vPC, GIR, and vPC Peer-Link as an Underlay Network Backup Path. In addition, this section starts by explaining the standard-based EVPN ESI Multi-homing solution. It also introduces an EVPN Multi-Site Data Center Interconnect (DCI) solution. In addition, this part explains Tenant Routed Multicast (TRM).
Each chapter includes various configuration and verification examples as well as traffic captures.
