End Users IPv6 Training by Hellenic IPv6 Task force
Today the Hellenic IPv6 Task force organized a training day for end users. Most of the presentations were entry level, since they were targeting end users, but most of them were very interesting. I was happily surprised by Cosmote‘s presentation on their mobile IPv6 tests using native IPv6 and NAT64.
My presentation was about what is architecturally different inside an IPv6-enabled CPE. I tried to present topics like WAN addressing, LAN addressing, auto-configuration (SLAAC), DHCPv6 as well as some migration/tunneling techniques. There were lots of comments, a lot of interesting questions and I was happy to “provoke” an interesting exchange of ideas/perceptions on IPv4 NAT mainly due to the previous to last slide of my presentation 🙂
At the end of the event there was a draw and people got 4 IPv6-enabled CPEs produced by the company I work for (Gennet), 4 DSL accounts by OTE ready to use for OTE’s pilot IPv6 program and 5 IPv6 related books generously provided by Cisco.
My presentation: Defining an IPv6-ready CPE
All presentations: IPv6 End Users Training Day (2011)
On Friday(s) 27/05 and 03/06 I’ll be giving two more IPv6 presentations at University of Pireus: [oss-unipi] Event #26: Introduction to TCP/IP and IPv6. The first one will be introductory and the second one will be more technical and maybe workshop based. In the same day(s) there will also be in-depth technical IPv4 presentations by Apollon Oikonomopoulos. Be there if you like technical presentations!

IPv6 workshop at Fosscomm 2011
This weekend, 7-8 May 2011, I’ll be doing a workshop about “IPv6 usage on Linux” at Fosscomm 2011 conference. Fosscomm is the biggest Greek Open Source conference with lots of interesting presentations, workshops and events. In the spirit of enabling IPv6 wherever possible, I am very happy to have managed to enable IPv6 connectivity for the website of Fosscomm this year!
During the workshop I will try to show the necessary tools to use, debug network problems and configure various services for IPv6. My goal is to explain to participants the abolishment of NAT, introduce the concepts of SLAAC and DHCPv6 and show them how to configure their networks to effectively use IPv6. If there’s enough time some issues related to IPv6 security will also be discussed. Target audience is people who are not afraid of the command line, have basic networking skills and are eager to learn things regarding IPv6!
Unfortunately it was impossible to have IPv6 upstream connectivity at the LAB, so participants will be testing everything on an IPv6 enabled remote infrastructure. Due to the limited number of LAB computers and Virtual Machines available, only 35, there is a registration form for participants to fill in. Please take the time to fill in the form any specific topics that you would like the workshop to pay attention to.
The workshop is taking place on Saturday 07/05/2011 and it will start _exactly_ at 10:45 in order to take full advantage of the time given to us by Fosscomm’s organizers.
Workshop is supported by the Greek IPv6 Taskforce and there miiiight be IPv6-related material distributed to the participants.
Please don’t forget to fill in the registration form!!!

Assigning IPv6 addresses from Cisco BRAS
A sample config for PPPoE clients connecting to a Cisco BRAS. The following example uses Stateless Address Autoconfiguration (SLAAC) to provide an IPv6 /64 subnet to clients on their PPP interface and DHCPv6 for Prefix Delegation in order to provide to a /56 subnet to them.
ipv6 unicast-routing ipv6 general-prefix ISP-PREFIX 2001:DB8:BBBB::/48 ipv6 cef ipv6 dhcp pool v6dhcppool prefix-delegation pool v6prefixpool2 dns-server 2001:DB8:DDDD::1 dns-server 2001:DB8:EEEE::1 sip address 2001:DB8:CCCC::1 sip domain-name ipv6-test.example.com Interface FastEthernet0/0.100 [ snip ] ipv6 address ISP-PREFIX ::1:0:0:0:1/64 ipv6 enable ipv6 mtu 1492 ipv6 nd reachable-time 30 ipv6 nd ra-interval 10 ipv6 nd ra-lifetime 3600 ipv6 nd prefix 2001:DB8:AAAA:2222::/64 86400 3600 off-link ipv6 nd other-config-flag ipv6 dhcp server v6dhcppool !

As the above config is just an example it uses the appropriate address space that IPv6 provides for examples, 2001:db8::/32
Hope it helps someone…
