Hi Aaron,

I assume you mean topological aggregated customer entry points, where
you want "tie down" customer assignments so they share a common route
within your infrastructure. "Tie down" is not defined in the NRPM.

Would you create an example scenario under current policy where an ISP
has exhausted the IPv6 addresses for which it qualifies and can not
get more due to a reasonable use of tie downs?

Is there any other way to resolve the problem? For example, if
6.5.3(b) was replaced with permitting an additional allocation in
order to enlarge the ISPs holdings to what it could justify under, would that satisfy?
