what protocol is used for setting up the administrative tunnel in ipsec?
layer 2 tunneling protocol
bullet::::- internet protocol security (ipsec) was initially developed by the internet engineering task force (ietf) for ipv6, which was required in all standards-compliant implementations of ipv6 before made it only a recommendation. this standards-based security protocol is also widely used with ipv4 and the layer 2 tunneling protocol. its design meets most security goals: authentication, integrity, and confidentiality. ipsec uses encryption, encapsulating an ip packet inside an ipsec packet. de-encapsulation happens at the end of the tunnel, where the original ip packet is decrypted and forwarded to its intended destination.

internet protocol security (ipsec) was originally developed for ipv6, but found widespread deployment first in ipv4, for which it was re-engineered. ipsec was a mandatory part of all ipv6 protocol implementations, and internet key exchange (ike) was recommended, but with rfc 6434 the inclusion of ipsec in ipv6 implementations was downgraded to a recommendation because it was considered impractical to require full ipsec implementation for all types of devices that may use ipv6. however, as of rfc 4301 ipv6 protocol implementations that do implement ipsec need to implement ikev2 and need to support a minimum set of cryptographic algorithms. this requirement will help to make ipsec implementations more interoperable between devices from different vendors. the ipsec authentication header (ah) and the encapsulating security payload header (esp) are implemented as ipv6 extension headers.
