Remote Network Monitoring (RMON) Protocol Identifiers for IPv6 and
Multi Protocol Label Switching (MPLS)
Status of this Memo
This memo provides information for the Internet community. It does
not specify an Internet standard of any kind. Distribution of this
memo is unlimited.

Abstract
This memo defines additional (to those in RFC 2896) protocol identifier examples for IP version 6 and MPLS protocols. These can be used to produce valid protocolDirTable INDEX encodings, as defined by the Remote Network Monitoring MIB (Management Information Base) Version 2 [RFC2021] and the RMON Protocol Identifier Reference [RFC2895].
This document contains additional (to those in RFC 2896) protocol
identifier macros for well-known protocols. A conformant
implementation of the RMON-2 MIB [RFC2021] can be accomplished
without the use of these protocol identifiers, and accordingly, this
document does not specify any IETF standard. It is published to
encourage better interoperability between RMON-2 agent
implementations, by providing RMON related IPv6 and MPLS protocol
information.

1. 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].
2. Overview
This memo defines basic protocol identifiers for IP version 6 and MPLS protocols.
The "Remote Network Monitoring MIB Protocol Identifier Macros" [RFC2896], defines various protocol identifiers. The syntax of the protocol identifier descriptor is defined in the RMON Protocol Identifier Reference [RFC2895]. The reader should be familiar with these documents.
The intent of this document is not to adapt each protocol identifier defined in the RFC 2895 and in the RFC 2896 to IP version 6, but to define protocol identifiers for IP version 6 protocols and for MPLS protocol.
3. Relationship to the Remote Network Monitoring MIB
RMON MIB implementations use protocol identifiers to describe unambiguous capabilities in protocolDirTable entries.
4. MPLS layer protocol identifiers
This section defines protocol identifiers for MPLS with unambiguous names to distinguish MPLS Unicast from MPLS Multicast.

CHILDREN
"Children of 'ip6' are selected by the value in the Protocol
field (one octet), as defined in the PROTOCOL NUMBERS table
within the Assigned Numbers Document.
The value of the Protocol field is encoded in an octet string as
[ 0.0.0.a ], where 'a' is the protocol field.
Children of 'ip6' are encoded as [ 0.0.0.a ], and named as 'ip6
a' where 'a' is the protocol field value. For example, a
protocolDirID-fragment value of:
0.0.0.1.0.0.0.41.0.0.0.58
defines an encapsulation of IPv6-ICMP (ether2.ip6.icmp6)"
ADDRESS-FORMAT
"16 octets of the IPv6 address, in network byte order. Each ip
packet contains two addresses, the source address and the
destination address."
DECODING
"Note: ether2.ip.ipip6.udp is a different protocolDirID than
ether2.ip6.udp, as identified in the protocolDirTable. As such,
two different local protocol index values will be assigned by
the agent. E.g., (full INDEX values shown):
ether2.ip.ipip6.udp =
16.0.0.0.1.0.0.8.0.0.0.0.41.0.0.0.17.4.0.0.0.0
ether2.ip6.udp =
12.0.0.0.1.0.0.0.41.0.0.0.17.3.0.0.0 "
