  1. IPv6 activities in Greece Dimitrios Kalogeras, Ph.d

  2. Agenda • Greek Research Network • Differences betweenIPv4 andIPv6 • IPv6in GRNET • GRNET member of 6net • GRNET2 • IPv6 in AIX • IPv6 in SEEREN • 6PE over CsC • QoS and IPv6

  3. GRNET • The Greek NREN • Presence all over Greece • 80 universities and research institutes • Backbone for schools

  4. IPv4 / IPv6 differences • Bigger but less complex headers • No new routing protocols • Adapted to carry bigger addresses • Security is implied even in routing protocols with IPSEC

  5. IPv6 in GRNET • First deployment of an overlay topology with tunnels and connectivity with 6bone. • Single node in GRnet • Gain experience with the new protocols and operational practice with management tools. • Initial service deployment with DNS • Preparation of RFP for IPv6 capable routers • Receive normal IPv6 prefixes form RIPE • Prepare an addressing plan for a /32 network ( ~ 4 billion addresses

  6. GRNET member of 6net • 6net: a FP5 project for a pan-European IPv6 network • Gain experience and knowledge through interaction with other NRENs and Cisco. • Adopt new techniques and practices for routing and operations ( i.e. embedded-RP in multicastv6, security etc) • GRnet active in QoS, applications, management and Security WP • GRnet prepares a pilot of transitioning a big operational network: the Greek school network

  7. GRNET2 • The new network is built with IPv6 support in mind. • Campus networks start connecting with IPv6 and transiting services in IPv6 also. • GRNET uses IS-IS and BGP-MP as routing protocols

  8. IPv6 in AIX • Aix is the Athens Internet Exchange • It is implemented by a L2 switch • Separate port of IPv6 aware traffic • INCENTIVE :No membership fees for IPv6 port • Experimental peering with a commercial ISP

  9. SEEREN and IPv6 • Originally not planned to provide IPv6 • Implemented with an MPLS based technology: Carrier Supporting Carrier (CSC) • CSC is an MPLS IPv4 based tunnel technology • Is it possible to provide IPv6 to the end users without traditional tunnels when the Carrier does not support IPv6 ? • YES !!! With a lot of innovation and troubleshooting of Cisco and our colleagues in AMREJ • 6PE over CSC - Not a simple solution

  11. IPv6 and QoS • Test QoS implementation in Cisco hardware platforms • Provide feedback to Cisco for problems in QoS handling when IPv6 is in use. • Finally fixed in the latest IOS.
