Deploying Juniper Data Centers with EVPN VXLAN (Early Release)

Deploying Juniper Data Centers with EVPN VXLAN is designed for engineers and architects designing, deploying, and/or maintaining small to large data centers. This book will increase productivity and streamline processing and communication by helping you understand BGP EVPN-based VXLAN, data center design, and deployment using Junos OS/EVO and interconnecting multiple data centers for various deployment applications. Aninda Chaterjee's straightforward prose and industry experience also gives you the foundational knowledge necessary for Juniper Data Center certification from the JNCIA-DC to the JNCIE-DC.
