Fred,

Thanks for the clarification.  Our next revision will take care of this
error in the document if ISATAP is agreed upon by the group to be
included for use in the home.

I asked for ISATAP to show up in the CPE Rtr document, but
I asked for it to show up inside the customer site; not on
the provider side. ISATAP is for host<->router or host<->host;
it is not for router<->router. So, the time ISATAP would be
used in the provider network is when the CPE device is a host
and not a router.

On the customer side, the CPE router can serve as the ISATAP
router and can be discovered by dual-stack hosts within the
customer network. But, that arrangement would not be visible
within the provider network.
