INTERNET-DRAFT VRRP unified MIB June 6, 2004
Abstract
This specification defines a Management Information Base (MIB) for
use with SNMP-based network management. In particular, it defines
objects for configuring, monitoring, and controlling routers that
employ the Virtual Router Redundancy Protocol for both IPv4 and IPv6
as defined in RFC 3768 and RFC xxxx ( RFC-editor, this is currently
draft-ietf-vrrp-ipv6-spec-06.txt ). This memo obsoletes RFC 2787.

1. Introduction
VRRP protocols as defined in RFC 3768[5] and draft-ietf-vrrp-ipv6-
spec-06.txt [6] are inherently IP version specific.Though both the
protocols are similar they are not identical and can coexist on a
network element. RFC2787 [7] defines managed objects that are
specific to VRRP protocol for IPv4 networks as defined in RFC 3768
[5]. This document defines an IP version independent managed objects
for configuring and monitoring VRRP protocols.
VRRP over IPv4 (VRRPv2) and VRRP over IPv6 (VRRPv3) protocols are
similar in operation to an extent and hence the MIB defined has
common groups that should be implemented by devices running either of
the VRRP over IPv4 and IPv6 protocols. This specification also
defines MIB groups that are specific to a particular VRRP protocol
and should only be implemented in devices supporting the specified
version of VRRP protocol.
Tata [Page 2]
INTERNET-DRAFT VRRP unified MIB June 6, 2004
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD, "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [1].
3. Relationship to RFC 2338
RFC2787 [7] defines managed objects for VRRP over IPv4 and has been
deprecated by this memo.
4. Relation to Interface Group (IF-MIB)
Since a router can be participating in VRRP on one or more physical
interfaces, "ifIndex" is used as an index into the tables defined in
the VRRP MIB.
5. Multi-Stack Implementations
This MIB is designed to support Multi-Stack implementations that run
VRRP over IPv4 and IPv6 protocols. IP version, VRID and ifIndex are
used to uniquely identify rows in a multi stack implementation.
6. VRRP MIB Structure
The VRRP MIB contains three groups:
- vrrpOperations Group: Objects related to VRRP router's
configuration and control.
- vrrpStatistics Group: Objects containing information useful in
monitoring the operation of VRRP routers.
- vrrpNotifications Group: Consists of objects and definitions
for use in SNMP notifications sent by VRRP routers.
Tables in the MIB include the following:
(1) The vrrpOperationsTable, which contains objects that define the
operational characteristics of a VRRP router. Rows in this table
correspond to instances of virtual routers.
(2) The vrrpRouterStatisticsTable which contains the operating
statistics for a VRRP router.
(3) The vrrpAssociatedIpAddrTable, contains the addresses of the
virtual router(s) that a given VRRP router is backing up. This
table is required only for VRRP for IPv4 implementations.
7. VRRP MIB Table Design
Tata [Page 3]
INTERNET-DRAFT VRRP unified MIB June 6, 2004
The tables in the VRRP MIB are structured with the assumption that a
VRRP network management application would likely be designed to
display information or provide configuration about a VRRP router
over a IP version "per-virtual-router basis". Thus, the tables
defined in the MIB consist of conceptual rows which are indexed in a
manner to present a view of individual virtual routers with a minimal
number of SNMP operations.
8. VRRP Multistack Scenario
The following section provides examples of how some of the objects in
this MIB are instantiated.
KEY:
----
The labels in the following tables and diagrams correspond to the
actual MIB objects as follows:
IpVer = vrrpOperationsIpVersion
if = IfIndex
VrId = vrrpOperationsVrId
State = vrrpOperationsState
Prior = vrrpOpeartionsPriority
AddrType= vrrpOperationsIpAddrType
IpAddr = vrrpOperationsMasterIpAddr
The following figure shows a hypothetical network with two VRRP
routers configured with two virtual routers. Addresses in '()'
indicate the address of the default gateway for a given host, H1 - H4
are IPv4 hosts and H5 to H8 are IPv6 hosts. In the diagram,
"Interface" is used in the context defined in IF-MIB.

NOTES:
1) "I1" and "I3" are used to designate IF indices on each respective
routers IPv4 interfaces.
2) "I2" and "I4" are used to designate IF indices on each respective
routers IPv6 interfaces.
3) For "State": M = Master; B = Backup.
4) In the vrrpOperationsTable, a "priority" of 255 indicates that
the respective router owns the IP address, e.g., this IP
address is native to the router (i.e., "the IP Address Owner" ).

transitions may not be immediate; they sometimes depend on
other factors, such as the interface (IF) state.
The `vrrpOperAdminState' object must be set to `down'

"The row status variable, used in accordance to

The rowstatus of a currently active row in the
vrrpOperTable is constrained by the operational state of
the corresponding virtual router.
When `vrrpOperRowStatus' is set to active(1), no other
objects in the conceptual row, with the exception of
`vrrpOperAdminState', can be modified. Prior to setting
the `vrrpOperRowStatus' object from `active' to a
different value, the `vrrpOperAdminState' object must be
set to `down' and the `vrrpOperState' object be
transitioned to `initialize'.
Tata [Page 14]
INTERNET-DRAFT VRRP unified MIB June 6, 2004
To create a row in this table, a manager sets this object
to either createAndGo(4) or createAndWait(5). Until
instances of all corresponding columns are appropriately
configured, the value of the corresponding instance of the
`vrrpOperRowStatus' column will be read as notReady(3).
In particular, a newly created row cannot be made
active(1) until (minimally) the corresponding instance of
`vrrpOperVrId' has been set and there is at least one
active row in the `vrrpAssoIpAddrTable' defining an
associated IP address for the virtual router."

10. Security Consideration
There are a number of management objects defined in this MIB module
with a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations. These are the tables and objects and their
sensitivity/vulnerability:
A number of objects in the vrrpOperationsTable possess the read-
create attribute. Manipulation of these objects is capable of
affecting the operation of a virtual router.
Specific examples of this include, but are not limited to:
o The vrrpOperationsAdminState object which could be used to
disable a virtual router.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPSec),
even then, 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.
It is RECOMMENDED that implementers consider the security features
as provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
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.
