SNMP Transition Tool Management of IPv6 Networks with IPv4/IPv6 SNMP Gateway Wiktor Procyk wiku@man.poznan.pl Zagreb, TERENA, May 2003 Wiktor Procyk <wiku@man.poznan.pl> 1

Introduction IPv6 is the „next generation” protocol designed by IETF to replace the current IPv4 - since January 1995 - more and more popular regular service - no support for IPv6 in commercial management platforms Zagreb, TERENA, May 2003 Wiktor Procyk <wiku@man.poznan.pl> 2

No Support for IPv6 in Management Platforms Management platforms: • HP OpenView • Tivoli NetView • Cisco CiscoWorks • IPSWITCH WhatsUp Zagreb, TERENA, May 2003 Wiktor Procyk <wiku@man.poznan.pl> 3

Possible Solution – Dual Stack IPv4/6 IPv4/6 network if IPv6 routing network process fails IPv6 only network Network Management Station Zagreb, TERENA, May 2003 Wiktor Procyk <wiku@man.poznan.pl> 4

The Idea of SNMP Transition Tool The main purpose of the development the SNMP Transition Tool is to enable the existing IPv4 network management platforms to monitor and configure the native IPv6 networks. The SNMP Transition Tool will translate SNMP protocol messages between IPv4 and IPv6 networks using its Address Translation Table. Zagreb, TERENA, May 2003 Wiktor Procyk <wiku@man.poznan.pl> 5

Future Development • Extend tool with new modules – DNS, 6tunnel, etc • Trap forwarding • SubAgent – collaborates with any SNMP agent AgentX protocol compatible • Automatic address configuration • MIB conversions – lots of problems to solve, e.g. see RFC 2962 - "An SNMP Application Level Gateway for Payload Address Translation" Zagreb, TERENA, May 2003 Wiktor Procyk <wiku@man.poznan.pl> 15
