IPv6 initiatives

• 6Bone
• Testbed for IPv6, built using a mesh of IPv6
  tunnels over IPv4 using the current Internet.
• 6REN
• ESnet initiative Research and education network
  using native IPv6. Production quality.
• Need for at least one exchange point to connect
  IPv6 networks together 6TAP

3
6TAP goals

• Exchange point for IPv6 networks
• Located at the Chicago NAP (Ameritech) at the
  Startap (ATM exchange)
• First phase is a single router receiving all ATM
  IPv6 PVCs
• ESNet is providing transit trafic to the 6Bone

4
6TAP architecture

• RE network already using v4 over ATM to reach
  StarTAP simply sets up a v6 ATM PVC path to the
  6TAP router

Peering
Native IPv6 peers

Wide area ATM links from StarTAP participants
worldwide
Native IPv6 peer

• IPv6 peers can immediately get access to other
  IPv6 peers by establishing only one direct
  peering with the 6TAP router.
• The 6TAP router will provide IPv6 routing
  information and transit traffic forwarding

6
6TAP operations

• Equipment and operational support are being
  provided by
• Router ESnet
• Route Server
• Viagénie under a Canarie project will develop and
  provide an IPv6 route server, based on the MERIT
  MRT project.
• Sun will provide servers for the route server
• Registry QWEST (continuation of work started at
  ISI)
• ATM switches/ports NSF (à la Star TAP)

7
6TAP operations

• ESnet provides IPv6 routing and transit between
  6TAP peers and non 6TAP 6Bone/6REN peers (as well
  as to ESnet sites).
• ESnet operations provides 24x7 monitoring of the
  6TAP router.

8
6TAP BGP peering

• Inbound route announcements
• will be filtered by prefix they must be a
  registered 6bone pTLA or a registry assigned
  sub-TLA
• Outbound route announcements
• will be the entire IPv6 BGP routing table
  filtered on registered prefix and length special
  cases are handled upon request.

9
6TAP services

• Web page at http//www.6tap.net
• For establishing BGP peering sessions.
• Route announcements
• point-to-point address pref
• AS number
• Contact info
• etc...
• Looking glass for routing info

6TAP services

• Looking glass for routing info
• BGP peering status (up/down)
• MRTG Stats
• additional polling variable requests will be
  considered

6TAP operations

• The 6TAP router supports native IPv6 peerings
  only no tunneled IPv6 connections.
• A dedicated server will provide IPv6 tunnels to
  sites that do not have ATM connectivity to the
  StarTAP

15
6TAP operations

• 6TAP tunnel service
• an extension of the 6TAP native link service
• enable IPv6 over IPv4 tunnel connections to the
  6TAP
• project done by Viagénie
• available by the end of the century!

16
Tunnel peering to the 6TAP

• Cisco router provides IPv4 connectivity for the
  tunnel server
• Tunnel server has native IPv6 connectivity to
  the 6TAP router
• Tunnel server provides IPv6 connectivity to
  sites without ATM links to the StarTAP

17
6TAP participants

• Current participants

APAN Japan APAN Korea ESNET NTT-ECL
vBNS SingAREN, Singapore Univ. of
Wisconsin-Madison

• Soon to be connected
• CAnet3
• others

Conclusion

• 6TAP IPv6 exchange
• Native IPv6 links (now)
• Tunneled IPv6 links (soon)
• Route server and registry (later)
