WIDE NLA1 Activity Report


Brief Intrduction about WIDE-NLA1


WIDE-JP was allocated sTLA address (2001:200::/35) space from APNIC in 1999/08/13. And after some discussions, WIDE-JP decide to allocate sTLA address for its customers (mainly for accademic/non-profit organizaions). WIDE-NLA1 is part of NLA1 allocation from WIDE-JP and its ipv6 prefix is 2001:200:0100::/40.

Assignment History


WIDE-NLA1 has started customer allocation from 2000/01/07 and there allocated 22 organizations(2001/01/06).

Network Topology


Bassically WIDE IPv6 network consists of WIDE-POPs that are located all over Japan and LAX and provide IPv6 connectivity such as OC-3 ATM, Gigabit Ethernet, FastEthernet and IPv6 over IPv4 tunnels(mainly for customers). As the following figure shows, almost POPs are connected with OC-3 ATM (and of course native IPv6 connection) ,partly using JGN (Japan Gigabit Network, which is national fund testbed network). And we are now try to cease IPv6 over IPv6 tunnels within POPs.

Routing


WIDE-NLA1 is currently using 3 routing protocols in its IPv6 netwoks.

Trouble


In the term of Routing, OSPFv3 is not stable at the begging of its experience (2000/05-) and it happed routing loops/missing routes due to implementation issue.
