Cheat sheets, study guides, and practice tests built by engineers with real certifications.
It walks you through building a full Cisco SD-Access virtual lab for self-practice: Catalyst Center, ISE, and Catalyst 9000v switches running on EVE-NG and ESXi. You get the resource sizing, the topology, the connectivity map, and working config for the fusion router, NAT router, and border node. Built for CCNP Enterprise and CCIE candidates who want hands-on fabric practice without buying hardware.
It's a cheat sheet and a study guide in one. You get EIGRP from the ground up: how it picks a path, how DUAL works, the timers, the tables, authentication, and the config commands you'll actually type on a router. Written for CCNA and CCNP students, useful for anyone who touches Cisco routing.
