The recording of last week's seminar on Introduction to DMVPN for CCIE R&S v5 Candidates is now available to view here. This is the first of many new free seminars on new topics that have been added to the CCIE R&S version 5 blueprint. New upcoming sessions will include IPv6 First Hop Security, IPsec LAN-to-LAN tunnels, GET VPN, IGP Convergence & Scalability, and BGP Convergence & Scalability, just to name a few. Feel free to submit requests for additional topics in the comments below.
Good luck in your studies!
