Re: Misconceptions, was: IPv6 RA vs DHCPv6 - The chosen one?

Sounds like we have one group saying that IPv6 is too complicated and
that all the "overhead" of IPv6 had resulted in slow adoption.

Meanwhile we have others saying it doesn't have enough functionality,
and should also include IGP.

Seems like IPv6 as it is has struck a balance somewhere in the middle.
 It's never going to be the perfect solution for every situation.

There is a lot of academic and theoretical argument being made here,
but not so much on the practical application side.  I think this
discussion went down hill when we started seeing people point to
"evidence" that IPv6 is "broken" being special use cases that IPv4
can't even handle properly.

Well the only reason why you still have a good night sleep with the primary path in flames and all those in stone 
carved static routes is that your server is connected via ether channel to a couple of boxes with dual RPs and 
redundant power supplies running VSS or vPC and routers running vrrp
All of this just because the end station just can't route around a failed link
