Arie -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Edward Iong Sent: Tuesday, November 16, 2010 08:14 To: [email protected] Subject: [c-nsp] IPv6 deployment Dear All, We are planning to implement IPv6 to our existing IPv4 network. There are several things I would like to ask:- 1. Can IPv4 and IPv6 devices exist at the same time in the same LAN? and can they communicate with each other? [Arie Vayner] Yes, you can have IPv4 and IPv6 hosts on the same LAN, but they cannot communicate with each other directly. Most likely what you are looking for is to deploy your hosts in dual-stack mode, meaning they would have, at the same time, an IPv4 and an IPv6 address, and the hosts would select which one to use for a specific session (based on things such as DNS or other higher layer information) 2. If both IPv4 and IPv6 devices can be in the same LAN, what kind of rounting technology can route the ip packet? [Arie Vayner] IPv6 can use most of the same routing protocols but with some extensions. BGP, OSPF (v3...) ISIS and EIGRP can be used for IPv6. Also, RIP (RIPng) is possible. It works more or less the same way it does for IPv4, but there are some differences, and design considerations for each of the protocols. 3. To route the traffic to the other LAN through WAN(MPLS), is it 6to4 will need to be in place? [Arie Vayner] 6to4 is a tunneling technology for passing IPv6 traffic through an IPv4 only transient network. Other tunneling technologies can be used and each one has a different native application (for example hosts in a corporate LAN would most likely use a different technology than residential ADSL CPEs...) Also, if you manage the MPLS core, then there are 6PE and 6VPE which allow core networks to support IPv6 through MPLS. 4. To access internet, it points to our PIX instead of PE router(MPLS), so is it I will need to implement 6to4 as well(if ISP can only provide ipv4 public address)? [Arie Vayner] Most likely the right way would be to work with your ISP (or other ISP...) to get IPv6 support... You could also use some temporary tunneling solution. 5. We are using Microsoft IAS for Wireless connection and network device access authentication. If we implement IPv6, will IAS support IPv6? [Arie Vayner] No clue... sorry. 6. Will PIX support IPv6? will have many site2site vpn connection. [Arie Vayner] You should look at ASA or maybe ASR1K If anyone who has experiences in IPv6 implementation project, please let me know as well.
