Description of Working Group:

The Layer 2 Tunneling Protocol (L2TP), defined in RFC2661 (http://www.ietf.org/rfc/rfc2661.txt) is a protocol for tunneling PPP (RFC 1661) sessions over various network types. The group will provide a forum for discussion and development of extensions to L2TP, and actively advance the L2TP base protocol to Internet Standard.

The group will:

Define and advance standard MIB for L2TP management.

Produce documents describing how L2TP operates over link types other than IP (e.g., ATM, Frame Relay, etc.)

Identify and define specific parameters and modes of IPsec in order to aid interoperability when IPsec is used to secure L2TP traffic.

Define and review the definition of any additional IETF AVPs which are of interest to the group.
