October 2013 Locator/ID Separation Protocol (LISP) MIB
This document defines the MIB module that contains managed objects to
support the monitoring devices of the Locator/ID Separation Protocol
(LISP). These objects provide information useful for monitoring LISP
devices, including determining basic LISP configuration information,
LISP functional status, and operational counters and other

This document describes the Management Information Base (MIB) module
for use with network management protocols in the Internet community.
Specifically, the MIB for managing devices that support the
Locator/ID Separation Protocol (LISP) is described.
LISP [RFC6830] specifies a network-based architecture and mechanisms
that implement a new semantic for IP addressing using two separate
name spaces: Endpoint Identifiers (EIDs), used within sites, and
Routing Locators (RLOCs), used on the transit networks that make up
the Internet infrastructure. To achieve this separation, LISP
defines protocol mechanisms for mapping from EIDs to RLOCs.
From a data-plane perspective, LISP traffic is handled exclusively at
the network layer by devices performing Ingress Tunnel Router (ITR)
and Egress Tunnel Router (ETR) LISP functions. Data-plane operations
performed by these devices are described in [RFC6830]. Additionally,
data-plane interworking between legacy (Internet) and LISP sites is
implemented by devices performing Proxy ITR (PITR) and Proxy ETR
(PETR) functions. The data-plane operations of these devices is
described in [RFC6832].
From a control-plane perspective, LISP employs mechanisms related to
creating, maintaining, and resolving mappings from EIDs to RLOCs.
LISP ITRs, ETRs, PITRs, and PETRs perform specific control-plane
functions, and these control-plane operations are described in
[RFC6830]. Additionally, LISP infrastructure devices supporting LISP
control-plane functionality include Map-Servers and Map-Resolvers,
and the control-plane operations of these devices are described in

3. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580

5. LISP MIB Objectives
The objectives for this LISP MIB module are to provide a read-only
mechanism to support the following functions:
o Provide a means for obtaining (read-only) a current status of LISP
features enabled on a device, and (read-only) a current status of
configuration attributes related to those features. As one
example, this MIB could determine the ON/OFF status of LISP
features such as ITR, ETR, PITR, PETR, MS, or MR support,
specifically as related to IPv4 or IPv6 address families as well
as the LISP Canonical Address Format (LCAF) [LCAF] with IANA
assigned Address Family Number 16387. Other examples could
include obtaining the (read-only) status of whether RLOC-Probing
is enabled, obtaining the status of whether the use of a PETR is
configured, and obtaining the (read-only) values of other related
attributes such as the map-cache limit value, or a mapping time-
to-live (TTL) value.
o Provide a means for obtaining (read-only) the current attributes
of various LISP tables, such as the EID-to-RLOC policy data
contained in the map-cache, or the local EID-to-RLOC policy data
contained in the mapping-database.
o Provide a means for obtaining (read-only) the current operational
statistics of various LISP functions, such as the number of
packets encapsulated and decapsulated by the device. Other
counters of operational interest, depending on LISP function,
include things like the current number of map-cache entries, and
the total number and rate of map-requests received and sent by the
6. Structure of LISP MIB Module
6.1. Overview of Defined Notifications
No LISP MIB notifications are defined.
6.2. Overview of Defined Tables
The LISP MIB module is composed of the following tables of objects:
lispFeatures - This table provides information representing the
various lisp features that can be enabled on LISP devices.
lispIidToVrf - This table provides information representing the
mapping of a LISP Instance ID to a VRF (Virtual Routing and
lispGlobalStats - This table provides global statistics for a given
Instance ID per address family on a LISP device.
lispMappingDatabase - This table represents the EID-to-RLOC database
that contains the EID-Prefix to RLOC mappings configured on an
ETR. In general, this table would be representative of all such
mappings for a given site to which this device belongs.
lispMappingDatabaseLocator - This table represents the set of
routing locators contained in the EID-to-RLOC database configured
on an ETR.
lispMapCache - This table represents the short-lived, on-demand
table maintained on an ITR that stores, tracks, and times-out EID-
lispMapCacheLocator - This table represents the set of locators per
EID-Prefix contained in the map-cache table of an ITR.
lispConfiguredLocator - This table represents the set of routing
locators configured on a LISP device.
lispEidRegistration - This table provides the properties of each
EID-Prefix that is registered with this device when configured to
be a Map-Server.
lispEidRegistrationEtr - This table provides the properties of the
different ETRs that send registers, for a given EID-Prefix, to
this device when configured to be a Map-Server.
lispEidRegistrationLocator - This table provides the properties of
the different locators per EID prefix that is registered with this
device when configured to be a Map-Server.
lispUseMapServer - This table provides the properties of all Map-
Servers that this device is configured to use.
lispUseMapResolver - This table provides the properties of all Map-
Resolvers that this device is configured to use.
lispUseProxyEtr - This table provides the properties of all Proxy
ETRs that this device is configured to use.
