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.
