1 IPv6 Support and Auto-Config. LAC NIC VII October 26, 2004 Wilfried Woeberwoeber@cc.univie.ac.at

2 topics IPv6 capable OSes IPv6 capable applications End-System auto-configuration IPv6 capable routing nodes

3 (some) IPv6 capable OSes Operating System IPv6 capability IPv6 supported FreeBSD 3.x with KAME-Stack 4.x integrated communitycommunity Linux since Kernel 2.2.19 community various distributions Solaris 7 with patch 8 integrated SUN AIX since 4.3 IBM MS Windows 2000 MS Windows 9x/NT MSResearch IPv6 Stack Trumpet Winsock noTrumpet MS Windows XP integrated ( ipv6 install ) no (not yet, soon?)

4 IPv6 capable applications http related Server: Apache, Fnord!, thttpd Clients: Mozilla (1), Lynx, w3m, wMosaic, Internet Explorer (1) smtp, pop, imap Server: sendmail, qmail, exim, qpopper, cucipop, courier-*d Clients: fetchmail, Inframail, elm, pine, mutt nntp Server: INN, leafnode Client: slrn, tin telnet, ssh, ftp Server: proftpd, oftpd Client: lftp, ncftp others Bind, Squid, OpenLDAP, cvs, rat, vic, mpeg123, Quake, various IRC apps (refer to the v6 projects' application lists!) …..and many, many more, e.g. UMTS release 5 requires IPv6! (1) Beware, both prefer IPv6 connectivity!

5 Configuration stateless address autoconfiguration 1) duplicate address detection (link-local addr.) 2) host sends router solicitation packet 3) router sends router advertisment packet 4) host builds address from interface identifier (known) and prefix (sent by router with 3) 5) duplicate address detection again stateful address autoconfiguration DHCPv6 (work in progress...) …and all possible combinations…

6 Renumbering hosts stateless address autoconfiguration router Prefix Control Operations high security level:-) guard against replays -) authentication -) integrity check sent in ICMPv6-packets (type 138)

7 IPv6 capable Routers Software based routers: Many public domain packages which implement IGPs and EGPs (zebra, quagga, mrt,...) can be used on (unix-like) workstations Many public domain packages which implement IGPs and EGPs (zebra, quagga, mrt,...) can be used on (unix-like) workstations Hardware based routers: Most well-known vendors do already support (basic) IPv6 stuff Most well-known vendors do already support (basic) IPv6 stuff Cisco, Juniper, 6WIND, japanese products (Hitachi-NEC),...
