Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time.

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. -- MPLS unicast Stephan/Palet Expires September 2004 [Page 2] Internet Draft Protocol Identifiers for IPv6 and MPLS March, 2004 mplsu PROTOCOL-IDENTIFIER PARAMETERS { } ATTRIBUTES { } DESCRIPTION "MPLS Label Stack Encoding."

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.

Stephan/Palet Expires September 2004 [Page 3] Internet Draft Protocol Identifiers for IPv6 and MPLS March, 2004 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.
