Explore why virtual private networks use IPsec to create secure tunnels over shared networks, comparing AH and ESP: origin authentication, encryption, integrity, and tunnel versus transport modes.
Configure IKE phase 2 by creating pre-shared keys and transform sets with encryption and authentication, then set lifetime and idle time in seconds or kilobytes and generate traffic.
Learn how crypto ACLs drive VPN builds in IPsec, defining outbound and inbound interesting traffic with extended ACLs, and why careful mirror configurations and avoiding permit any are essential.
Learn to configure a crypto map on a router, turning an ACL into a crypto ACL, set a peer and a transform set, and apply the map to the interface.
Don't know what AH and ESP are? No problem! Join up right now and you will -- and you'll be notified of every new video I post to this course until its completion in about 10 days.
