More Hurdles - HW/SW -
Cisco
- Not stable. need to improve IOS
- Do not supply IPv6 for all current platforms
- Older platforms do not have upgrade path, new routers required
Microsoft
- Need to provide fully functional IPv6 implementation
- Currently includes IPv6, but it's somewhat hidden!
Unreliable & not fully supported software for routers and servers
Not sensible to run IPv4 and IPv6 on same equipment; too expensive to run two large networks simultaneously.
“Lack of support for IPv6 transport in 'large-scale' access technology products (ADSL, wireless LAN)"
