Explanation
Tunnel mode is used to create Virtual Private Networks for network-to-network communications between routers to link sites. Key Takeaway: IPSec is a protocol suite for securing Internet Protocol communications by authenticating and encrypting each IP packet of a data stream. It is a dual mode, end-to-end, security scheme operating at the OSI model Layer 3. In tunnel mode of the IPSec protocol, the entire IP packet is encrypted and/or authenticated. It is then encapsulated into a new IP packet with a new IP header. It is used to create VPN for network-to-network, host-to-network, and host- to-host communications.
