RE: IPv6 in the network, please

2004-11-10 11:56:28
So somebody needs to get Airespace's marketroids to slow down a little
bit:

P.S. Sincere thanks to the IETF61 NOC for making these efforts to get
IPv6 functional on the entire network - I'll try that new config now
from Lincoln.

Folks,

     To expand on Jeff's explanation of the IPv6 status here at
IETF61;
The entire network, both wired and wireless, was designed from the
get-go as being IPv6 capable. It also had a very real and major
requirement to be stable in the face of hundreds of clients all at
100% transmit power, rogue APs,  and all the other problems that have
plagued previous IETF wireless networks. The good folks at Airespace
seemed to have a system that met this goal, and as we all can see,
it indeed works well. 

     However, when we asked Airespace to join us in this adventure,
it
became clear that the "intelligence" of their system worked through
tracking IPv4 DHCP requests, and thus wouldn't work with IPv6. This
lack of IPv6 support was nearly a show stopper, however Airespace
jumped through some major hoops to design, implement, and deploy code
that monitors RAs and RSs specifically to handle IPv6 for this
network. 

     Like most brand new code, when we deployed it, we encountered
problems. Problems that lead to instability in ALL wireless network
access. After several long days and nights of working on this long
before the first attendees arrived (we've been on site since Tuesday
2nd - Election Day ;) we decided to disable the IPv6 support on the
wireless network, rather than risk the overall network stability.
Airespace continues to work on the problems, and we believe that we
have a reasonable interim solution.

     We have phased in a new image with limited deployment, which we
will
monitor. If we experience no problems, IPv6 will be back on the
wireless lan, however we need to maintain the overall stability of
the wireless network as our highest priority.

     For those who need IPv6 on wireless:

     SSID: ietf61v6
     WEP Key: thisisav6wlan
     Hex: 746869736973617636776c616e

     Coverage will be available in Georgetown, Lincoln, Jefferson,
Monroe, Military and Hemisphere. You should not associate with this
wireless network if you need stable IPv4. This is a dedicated
network with new AP's and a new controller. 

     My thanks to our volunteer staff who worked to deploy this
network
in the late hours last night (and very early hours this morning)
after the social event. 

     For those that are inconvenienced by the loss of IPv6, I
sincerely
apologize, and remind you that native IPv6 is available at every
wired port in the terminal room. 

     Thanks for bearing with us, and have a good meeting!

     - Ben Crosby
