IPv6 section of ARIN Number Resource Policy (Sec 6.5.1.1.c)

Hi,

This question is about the IPv6 section of ARIN Number Resource Policy 
Manual.

>From the manual (Section 6.5.1.1.c):

-----
6.5.1.1. Initial allocation criteria

c. Plan to provide IPv6 connectivity to organizations to which it will
assign IPv6 address space, by advertising that connectivity through its
single aggregated address allocation
-----

We have a problem with this policy and we would like to know if any other 
ISP experienced the same...

The problem raises when a RIR assign a /28 prefix (for example) to an ISP 
which has 3 internet links with 3 different carriers (tier 1 carriers, for 
example) using BGP publications.

Acording to ARIN (and most other RIRs) policy, the ISP must advertise 
through all the 3 links the /28 without the possibility of dissagregation. 
The problem with this policy is that by doing this, the ISP loses control 
of the traffic, not being able to distribute the traffic over the 3 
different links.

A /28 prefix may have a lot of incoming traffic associated to it, so I 
believe the dissagregation (subnets) of the prefix should be allowed by 
the policy.

What do you think? Do you have a similar problem?

Thanks,
Nicolas Antoniello.
