Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in TCP/IP-based internets.
In particular, it defines objects for managing networks using Layer 2
Tunneling Protocol.
This memo specifies a MIB module in a manner that is both compliant
to the SNMPv2 SMI, and semantically identical to the peer SNMPv1
definitions.

2.0 The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2271 [1].
o Mechanisms for describing and naming objects and
events for the purpose of management. The first
version of this Structure of Management Information
(SMI) is called SMIv1 and described in RFC 1155 [2],
RFC 1212 [3] and RFC 1215 [4]. The second version,
expires January 1999 [Page 3]
Internet Draft August 1998
called SMIv2, is described in RFC 1902 [5],
RFC 1903 [6] and RFC 1904 [7].
o Message protocols for transferring management
information. The first version of the SNMP
message protocol is called SNMPv1 and described in
RFC 1157 [8]. A second version of the SNMP message
protocol, which is not an Internet standards track
protocol, is called SNMPv2c and described in
RFC 1901 [9] and RFC 1905 [13]. The third version
of the message protocol is called SNMPv3 and
described in RFC 1906 [10], RFC 2272 [11] and
RFC 2274 [12].
o Protocol operations for accessing management
information. The first set of protocol operations
and associated PDU formats is described in
RFC 1157 [8]. A second set of protocol operations
and associated PDU formats is described in
RFC 1905 [13].
o A set of fundamental applications described in
RFC 2273 [14] and the view-based access control
mechanism described in RFC 2275 [15].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (e.g., use of Counter64). Some machine
readable information in SMIv2 will be converted into textual
descriptions in SMIv1 during the translation process. However, this
loss of machine readable information is not considered to change the
semantics of the MIB.
3.0 Overview
The objects defined in this MIB are to be used when describing Layer
Two Tunneling Protocol (L2TP) tunnels. The L2TP protocol is defined
in [16]. This MIB consists of four groups briefly described below:
l2tpConfigGroup
l2tpStatsGroup
expires January 1999 [Page 4]
Internet Draft August 1998
These two groups of objects provide information on the configuration,
state and statistics of the L2TP protocol, its tunnels and sessions.
These groups are mandatory for implementors of this MIB.
l2tpDomainGroup
This optional group of objects provides configuration, state and
statistical information for L2TP tunnel endpoint domains. A L2TP
tunnel endpoint domain is considered to be a collection of L2TP
devices typically belonging to a common administrative domain or
geographic location.
l2tpIpUdpGroup
This group provides the state and statistics information for L2TP
tunnels which are being transported by IP/UDP. This group is
mandatory for L2TP implementations that support L2TP over IP/UDP.
3.1 Relationship to the Interface MIB
This section clarifies the relationship of this MIB to the Interfaces
MIB [17]. Several areas of correlation are addressed in the following
subsections. The implementor is referred to the Interfaces MIB document
in order to understand the general intent of these areas.
3.1.1 Layering Model
This MIB contains several tables which are extensions to the
IP Tunnel MIB described in [18] which itself defines extensions
to the Interface MIB [17]. A L2TP tunnel and each of the PPP
sessions multiplexed within it are represented as separate
identifiable logical interface sub-layers. The tunnel and session
interfaces appear in the ifStackTable at different sub-layers
depending on the functionality the tunnel endpoint is providing
for each session. At the LAC end of a tunnel endpoint the tunnel
interface appears above the session interfaces. At the LNS end
of a tunnel endpoint the tunnel interface appears below the
session interfaces.
In the example diagram below, the interface layering is shown as it
appears at the LNS. Note that the L2TP tunnel interface is at the
bottom of the interface stack when the transport layer for L2TP is
IP/UDP. This is because tunneled traffic is forwarded to its
destination based on routing policy. However L2TP over transports
other than IP/UDP may define further sub-layer interfaces below
the tunnel interface.
expires January 1999 [Page 5]
Internet Draft August 1998
In both diagrams the acronym "LSI" is used to indicate "L2TP Session
I/F".

The ifStackTable is used to describe the layering of the interface
sub-layers. For the example given above the ifTable and ifStackTable
may appear as follows:

from the ifGeneralInformationGroup and one of the following three groups:
o ifPacketGroup OR

depending on the particular implementation.

high capacity packet groups) are to be interpreted and supported for both
L2TP tunnel interfaces and L2TP session interfaces.

3.2 Relationship to other MIBs
3.2.1 Relationship to the IP Tunnel MIB
The IP Tunnel MIB [18] describes tunnel interfaces that have an ifType
of tunnel(131). The IP Tunnel MIB is considered to contain a collection of
objects common to all IP tunneling protocols, including L2TP. In addition
to the IP Tunnel MIB, tunnel encapsulation specific MIBs (like this MIB)
extend the IP Tunnel MIB to further describe encapsulation specific
information. Implementation of the IP Tunnel MIB is required for L2TP
tunnels over IP.
3.3 L2TP Tunnel Creation
Tunnel creation is detailed for IP tunnels in the IP Tunnel MIB. The
creation of a tunnelIfEntry in [18] will have the side affect of
creating entries in the l2tpTunnelConfigTable, l2tpTunnelStatsTable
and the l2tpUdpStatsTable's.
expires January 1999 [Page 12]
Internet Draft August 1998
The creation of L2TP tunnel interfaces over transports other than IP
is expected to be defined in the MIB definition for that specific
L2TP tunnel transport.
