Paul the difference between IPv4 and IPv6, in this issue is NAT.

Fail over with v4 is done by simply changing the gateway for the NAT, 
which is a simple rule change.

With v6 we don't have nat, so you have to either have BGP and announce 
your range to your providers or you have to renumber your network if a 
provider fails.

I don't now anything about BGP, so I don't know how to set it up, so 
before I can move forward I need to understand this stuff.

People here have said that enterprise is dragging their feet.  Yes we 
are.  We just don't know how to do this stuff and we can't set it up 
even if we did.

I've been trying to figure out how to best address this stuff and 
realised that I've got lots of learning to go, and I suspect that there 
are dozens and dozens of others who are in the same boat.

I've also realised that in the enterprise space I have to now be 
thinking in terms of redundancy right to the edge for my little 
customers (1 to 5 computers in the office).

With v4 this is really really simple.  Just put in a Mikrotik router 
with a USB port and I can have fail over to 3G data to keep the phones, 
email and light web browsing alive until I can sort out what ever has 
caused the main data service to fail.

I can set up VPN links for services like phones and mail collection that 
will just reconnect automatically when a link fails.

I have no idea how to even design this stuff in a v6 world for a customer.

A year ago I approached both the local TAFE and University to find out 
about networking courses.  Great expense and many many many hours to do 
stuff that I know backwards, while v6 is a token gesture (as someone 
else already mentioned).

I guess my point here is that the resources are not actually easy to 
get, we don't quite seem to know what we actually need, the 'schools' 
aren't actually gearing up or geared up to address the education that 
industry like myself (and I know I'm just one small fish of  many 
thousands and thousands) actually needs.
