IP Traffic Tunneling from GRE to IPsec

IP Traffic Tunneling from GRE to IPsec explains how tunnel-based connectivity is created, secured, and managed in enterprise networks. Learners start with IP tunneling concepts and GRE operation, then compare VPN models before studying IPsec basics such as security associations, ISAKMP, IKEv1, IKEv2, encryption negotiation, and NAT traversal. The course links these concepts to practical route-based IPsec VPN configuration so learners can see how secure overlays transport traffic between sites. It supports ENCOR preparation while building practical knowledge for real-world network operations.

Keith Bogart

Course Instructor

Keith started his networking career as customer service representative at Cisco Systems in 1996. His desire to learn more soon led him to a position as a Cisco Technical Assistance Center (TAC) engineer on the “Dial-Access” team, and within six months he had obtained his Dial-ISP CCIE. He later became a network consulting engineer and obtained his CCNA certification while teaching the technologies to Cisco employees during his lunch breaks. Keith was the first instructor on Cisco’s TAC Training team, where he taught a wide range of internetworking topics and later developed and taught other courses such as routing protocols, LAN switching, MPLS, 802.1x, and CCNA. After almost 17 years with Cisco, Keith joined a small startup and focused on 802.11 Wi-Fi technologies, during which time he obtained his CWNA certification. He is now very happy to be working with as an instructor for Routing & Switching. Keith lives in Raleigh, North Carolina, with his wife, son, and daughter. When he is not teaching Bootcamps, Keith can be found at home with his family, reading, or working in the yard.
