OK, let's go over the reasons from an ISTP standpoint:
- L3 routing and firewalling upgrades required. Wait, your
6509/7206VXR support IPv6? Yeah....it does. Most of it in CPU. You
will be CRUSHED if you try to do what you are likely doing now as far
as PPS and ACLs in IPv6 without an upgrade to the latest gear.
- ISP support - how many of you actually have upstreams that fully
support IPv6? Do you really want to count on tunneling for your
- ARIN support - Really, guys? You complain about running out of
space, yet you want to bill the crap out of me to use "the solution"?
Give me a /32 PI for every /22 allocation I already have, for free,
and you might see some more people spending more time demanding that
their upstreams support IPv6, justifying IPv6 capable gear in upgrade
cycles, etc, etc (i.e.: reaching a carrier-class layer 3 tipping point
- SBC support: Why would they bother when the L3 isn't there in most
cases? Not a single one of my carriers supports IPv6, so why would I
even ask for it from my SBC?
I'm sure there's more, but that's off the top of my head. Bottom
line: we don't even have critical mass in basic L3 connectivity.
Could pushing it from the application side help? Probably. Is there
any current well justified business case? No. Not considering the
realities of business short-sightedness and budgetary constraints.
