RFC3919 RFC3919 � "Remote Network Monitoring (RMON) Protocol Identifiers for IPv6 and Multi Protocol Label Switching (MPLS)" � What is a protocol identifier ? – Codification – Defined in RFC 2896 and RFC 2895 � Why protocol identifiers ? – Encourage better interoperability between RMON-2 agent implementations – produce valid protocolDirTable INDEX encodings; – Usage in Remote Network Monitoring MIB (Management Information Base) Version 2 [RFC2021] � Why IPv6 ? – Avoid error during configurationIPIP6 IP6; � Success Story: – 56th IETF:6QM partners identify RMON MIBs where not able to describe IPv6 capabilities; – 57th IETF: individual submission draft-stephan-ipv6-protocol-identifier-00.txt – 58th IETF WG Item: draft-ietf-rmonmib-pi-ipv6-01.txt – After 59th IETF WG last call: draft-ietf-rmonmib-pi-ipv6-02.txt – Before 60th IETF IESG Evaluation; draft-ietf-rmonmib-pi-ipv6-03.txt and 04 – After 60th IETF: RFC Queue – Before 61th IETF: It gained RFC in October 2004. Its number is RFC3919. IETF & ITU Standardization Activities 3
