InterWorking Labs Issues Advisory Warning on IPv6 MIBs

InterWorking Labs warns that manufacturers are implementing obsolete versions of the IPv6 MIBs for SNMP

SCOTTS VALLEY, Calif. (September 11, 2006) - InterWorking Labs, developers of innovative products to measure, characterize, and debug  next generation network devices in enterprise communications networks, issued an Advisory Warning today regarding the implementation of the IPv6 MIBs.

IPv6 is a network layer protocol that specifies the format of packets and the addressing scheme.  IPv6 is the next generation network layer protocol from IPv4.  IPv6 and IPv4 are used in conjunction with TCP to form connections on the Internet and exchange data.  TCP/IP is considered a “core protocol” for the Internet.  The new IPv6 MIBs (management information base) define and organize the information required to manage, troubleshoot and diagnose IPv6 network operation.

"We have found many instances where developers have implemented the obsolete versions of these MIBs," explained Chris Wellens, President & CEO.  “This is costing the industry hundreds of thousands of dollars in wasted development work, not to mention the delays in deployment of IPv6."

The new, correct specifications for the IPv6 MIBs are:

  • RFC 4292 IP Forwarding Table MIB
  • RFC 4293 Management Information Base for the Internet Protocol (IP)
  • RFC 4022 Management Information Base for the Transmission Control Protocol (TCP)
  • RFC 4113  Management Information Base for the User Datagram Protocol (UDP)

These new IPv6 MIBs make the following RFCs obsolete:

  • RFC 4292 (obsoletes rfc2096)
  • RFC 4293 (obsoletes rfc2011, rfc2465, rfc2466)
  • RFC 4022 (obsoletes rfc2452, rfc2012)
  • RFC 4113 (obsoletes rfc2454, rfc2013)

"The newest MIBs provide indexing for both IPv4 and IPv6 in a single MIB.  The IP MIB also supports additional large counters and includes new MIB objects and tables to fully describe an IPv6 host stack.  These tables can also be useful in an IPv4 setting," explained Shawn Routhier, Editor of the newest IP MIB, RFC 4293. "Implementing the correct RFCs is essential for effective management of IP networks."
