Build a VXLAN BGP EVPN fabric on Nexus from scratch. Covers the OSPF underlay, BGP EVPN overlay, NVE configuration, distributed anycast gateway, and the verification commands that prove it actually forwards.
Operate Nexus spine/leaf fabrics without surprises. Covers vPC operational checks, port-channel hygiene, OSPF/BGP underlay verification, and failure drills before go-live.
Build a production-ready IOS-XE edge router. Covers secure management, IP SLA tracking for real failover, logging configuration, and common mistakes that break production.
