IPv6 in GANT

1
IPv6 in GÉANT

• DANTE Ana Romero
• 6DISS workshop, March 2006
• Kopaonik
• Presenting János Mohácsi NIIF/HUNGARNET

2
GÉANT2 pan-European Research Network successor
to GÉANT

• Connecting 34
• European Countries
• and 30 NRENs
• Mixture of leased circuits and dark fibre to
  provision current high bandwidth demands
• Juniper routers and Alcatel optical equipment

Backbone topology from Aug 2005
3
IPv6 implementation on GEANT

• Implementation of dual stack in all GEANT
  backbone in early 2003
• First NRENs v6 connected in spring 2003
  Renater (.fr) and RedIRIS (.es)
• GEANT IPv6 service operational since Oct 2003

IPv6 Connectivity in GÉANT
5
IPv6 connectivity to NRENs

• 30 out of 31 NRENs connected
• 27 out of 30 are native connections
• rest are tunnels
• 580 routes announced to NRENs
• Only 2000/4 prefixes between /19-/35 permitted
  

6
IPv6 connectivity to non-EU Research Networks (I)

• Abilene (US) gt All native connections examples
  of connectivity
• - ARIN Region DoD (22), VBNS (145),
  Univ.Wiscosin (2381), Univ.Indiana (22398)
• CLARA (LatinAmerica) gt Native
• LACNIC Region RNP (1916), Retina (3597)
• TEIN2 (South East Asia) gt Native
• APNIC Region Australia NREN (7570), Singapore
  NREN (7610)

7
IPv6 connectivity to non-EU Research Networks (II)

• ESnet (US) gt Native link
• Ca-net (CA) gt Native in two links
• SInet (JP) gt Tunnel in New York

8
IPv6 connectivity to ISP

• Providing free interconnection for European NRNs
  to the whole v6 internet
• Tunnel connections with ISPs
• Encouraging ISP to develop their networks in
  IPv6
• Access to commercial IPv6 networks

Multicast IPv6
13
Multicast IPv6 in GÉANT

• Native Multicast IPv6 across GÉANT backbone
• Pilot service ready since early 2005
• Test done in 2004 in collaboration with Multicast
  v6 TF
• Request for specific multicast v6 features to
  Juniper
• Several NRENs connected to the multicast IPv6
  enable core
• 12 NRENs already connected - 7 in native, rest in
  tunnels
• Connectivity to M6bone via Renater
• Native connectivity to Abilene

14
Future plans Embedded RP

• Interdomain multicast IPv6 implementing
  embedded RP
• interdomain solution where the RP can be
  selected when setting a session
• Available in JUNOS since 7.0
• Needs to be deployed in all the domains
• other vendors such as Cisco also support it

15
Conclusions

• GÉANT and NRENs leading IPv6
• Most of NREN IPv6 is deployed for a long time
• Encouraging to see how v6 traffic grows
• Work is still needed at the end user
• small proportion of end users connected
• develop IPv6 applications
• Multicast IPv6 new technology
• work needed in interdomain mcastv6 and
  applications
