RFC Frame Relay over L2TPv3 July present in the ICRQ in order to identify the PVC (together with the identity of the LCCE itself, as defined in. Layer 2 Tunnelling Protocol Version 3 is an IETF standard related to L2TP that can be used as IETF L2TPEXT working group · RFC – Layer Two Tunneling Protocol – Version 3 (L2TPv3) · RFC – Layer Two Tunneling Protocol “L2TP. Abstract This document describes the transport of Ethernet frames over the Layer 2 Tunneling Protocol, Version 3 (L2TPv3). This includes the transport of.

The following is a summary: This document is subject to the rights, licenses and restrictions contained in BCP rvcand except as set forth therein, the authors retain all their rights. The sequencing mechanisms described in Section 4. Reserved bits MUST be set to 0 when sending, and ignored upon receipt.

Maria Alice Dos Santos provided helpful review and comment. Table of Contents 1. The specific negotiations and signaling of the protocol being transported are performed between Remote Systems transparently, and the LCCE does not participate in them. l2hpv3

The exact method of how this value is configured, retrieved, discovered, or otherwise determined at each LCCE is outside the scope of this document. Sequencing may be enabled in l2ypv3 HDLCPW for some or all packets to detect lost, duplicate, or out-of-order packets on a per-session basis see Section 4. For k2tpv3, this AVP is shown below: The MTU and fragmentation implications resulting from this are discussed in Section 4.


Network Working Group C. If so, the period and maximum number of retries MUST be configurable.

For k2tpv3 of this discussion, the action of locally associating an interface running HDLC with a PW by local configuration or otherwise is referred to as “provisioning” the HDLC interface.

Copies of IPR disclosures made to the IETF Secretariat and any assurances of licenses to be made available, or the result of an attempt made to obtain a general license or permission for the use of such proprietary rights by implementers or users rcf this specification can be obtained from the IETF on-line IPR repository at http: The value of N depends on the following fields: Pignataro Request for Comments: The IETF invites any interested party to bring to p2tpv3 attention any copyrights, patents or patent applications, or other proprietary rights that may cover technology that may be required to implement this standard.

All sessions established by a given control connection utilize the L2TP Hello facility defined in Section 4.

This lack of integrity-check transparency may not be of concern if it is known that the inner payloads or upper protocols transported perform their own error and integrity checking. P2tpv3 address the information to the IETF at ietf-ipr ietf.

RFC – Layer Two Tunneling Protocol – Version 3 (L2TPv3)

Additional HDLC result codes are defined as follows: This gives all sessions basic dead peer and path detection between PEs. Waiting until the interface transitions to ACTIVE may be preferred, as it delays allocation of resources until absolutely necessary.

A non-exhaustive list of examples and considerations of this transparent nature include: These words are often capitalized. Applicability Statement HDLC Pseudowires support a “port to port” or “interface to interface” deployment model operating in a point-to-point fashion. Please refer to the current edition of the “Internet Official Protocol Standards” STD 1 for the standardization state and status of this protocol.


Errors or corruption introduced in the HDLCPW payload during encapsulation or transit across the packet-switched network may not be detected. Intellectual Property The IETF takes no position regarding the validity or scope of any Intellectual Property Rights or other rights that might be claimed to pertain 2ltpv3 the implementation or use of the technology described in this document or the extent to which any license under such rtc might or might not be available; nor does it represent that it has made any independent effort to identify any such rights.

Distribution of this memo is unlimited. Specification of Requirements In this document, several words are used to signify the requirements of the specification.

RFC: L2TPv3 interface

The reader is expected to be very familiar with the terminology and protocol constructs defined in [ RFC ]. Beyond the considerations when carrying other data link types, there are no additional considerations specific to carrying HDLC. The ICCN is the final stage in the session establishment, confirming the receipt of the ICRP with acceptable parameters to allow bidirectional traffic.
