1. Introduction
This document defines a portion of the Management Information Base
(MIB) for use with network management protocols in the Internet
community. In particular, it defines objects used for monitoring the
RPKI-Router Protocol [RFC6810].
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in RFC
2119 [RFC2119].
2. 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 [RFC2580].
3. Overview
The objects defined in this document are used to monitor the RPKI-
Router Protocol [RFC6810]. The MIB module defined here is broken
into these tables: the RPKI-Router Cache Server (Connection) Table,
the RPKI-Router Cache Server Errors Table, and the RPKI-Router Prefix
Origin Table.
The RPKI-Router Cache Server Table contains information about the
state and current activity of connections with the RPKI-router cache
servers. It also contains counters for the number of messages
received and sent, plus the number of announcements, withdrawals, and
active records. The RPKI-Router Cache Server Errors Table contains
counters of occurrences of errors on the connections (if any). The
RPKI-Router Prefix Origin Table contains IP prefixes with their
minimum and maximum prefix lengths and the Origin Autonomous System
(AS). This data is the collective set of information received from
all RPKI cache servers that the router is connected with. The cache
servers are running the RPKI-Router Protocol.
Two notifications have been defined to inform a Network Management
Station (NMS) or operators about changes in the connection state of
the connections listed in the RPKI-Router Cache Server (Connection)
Table.
4. Definitions
The following MIB module imports definitions from [RFC2578],
[RFC2579], [RFC2580], [RFC4001], and [RFC2287]. That means we have a
normative reference to each of those documents.
The MIB module also has a normative reference to the RPKI-Router
Protocol [RFC6810]. Furthermore, for background and informative
information, the MIB module refers to [RFC1982], [RFC4252],
[RFC5246], and [RFC5925].

encountered a discontinuity.
For objects that use rpkiRtrDiscontinuityTimer to
indicate discontinuity, only values received since
the time indicated by rpkiRtrDiscontinuityTimer are
comparable to each other. A manager should take the
possibility of rollover into account when
calculating difference values.
In principle, that should only happen if the
SNMP agent or the instrumentation for this
MIB module starts or restarts."

rpkiRtrCacheServerConnectionStateChange NOTIFICATION-TYPE
OBJECTS { rpkiRtrCacheServerConnectionStatus,
rpkiRtrCacheServerLatestSerial,
rpkiRtrCacheServerSessionID
}
STATUS current
DESCRIPTION "This notification signals a change in the status
of an rpkiRtrCacheServerConnection.
The management agent MUST throttle the generation of
consecutive rpkiRtrCacheServerConnectionStateChange
notifications such that there is at least a 5 second
gap between them.
If more than one notification has occurred locally
during that time, the most recent notification is
sent at the end of the 5 second gap and the others
are discarded."

STATUS current
DESCRIPTION "This notification signals that an RPKI cache
server connection is about to go stale.
It is suggested that this notification is
generated when the value of the
rpkiRtrCacheServerTimeToRefresh attribute
goes below 60 seconds.
The SNMP agent MUST throttle the generation of
consecutive rpkiRtrCacheServerConnectionToGoStale
notifications such that there is at least a
5 second gap between them.

STATUS current
DESCRIPTION
"The compliance statement for the rpkiRtrMIB module. There
are only read-only objects in this MIB module, so the
'ReadOnly' in the name of this compliance statement is there
only for clarity and truth in advertising.
There are a number of INDEX objects that cannot be
represented in the form of OBJECT clauses in SMIv2, but for
which there are compliance requirements. Those requirements
and similar requirements for related objects are expressed
below, in pseudo-OBJECT clause form, in this description:
-- OBJECT rpkiRtrCacheServerRemoteAddressType
-- SYNTAX InetAddressType { ipv4(1), ipv6(2), dns(16) }
-- DESCRIPTION
-- The MIB requires support for the IPv4, IPv6, and DNS
-- InetAddressTypes for this object.
-- OBJECT rpkiRtrCacheServerLocalAddressType

5. IANA Considerations
IANA has assigned the MIB module in this document the following
OBJECT IDENTIFIER within the SMI Numbers registry.
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
rpkiRtrMIB { mib-2 218 }
6. Security Considerations
There are no management objects defined in this MIB module that have
a MAX-ACCESS clause of read-write and/or read-create. So, if this
MIB module is implemented correctly, then there is no risk that an
intruder can alter or create any management objects of this MIB
module via direct SNMP SET operations.
Most of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. They are vulnerable in the
sense that when an intruder sees the information in this MIB module,
then it might help him/her to set up an attack on the router or cache
server. It is thus important to control even GET and/or NOTIFY
access to these objects and possibly to even encrypt the values of
these objects when sending them over the network via SNMP.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPsec),
there is no control as to who on the secure network is allowed to
access and GET/SET (read/change/create/delete) the objects in this
MIB module.
Implementations MUST provide the security features described by the
SNMPv3 framework (see [RFC3410]), including full support for
authentication and privacy via the User-based Security Model (USM)
[RFC3414] with the AES cipher algorithm [RFC3826]. Implementations
MAY also provide support for the Transport Security Model (TSM)
[RFC5591] in combination with a secure transport such as SSH
[RFC5592] or TLS/DTLS [RFC6353].
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
