Roberta:

Why is this an issue for BNG's in the 3GPP world and not elsewhere?

Yes you can install the aggregate route but you would need either another
dhc option that tells the BNG what aggregate route needs to be installed per
each customer or you have to do by manual configuration.

In my opinion using PD-exclude is operational much simpler

Roberta,

I don't see that a problem either because usually you can install an
aggregate route.

Behcet,
  the reason why you may need to have a single prefix instead of two per
customer is in order to have just a single route to install on the BNG
instead of two.

Hi Roberta,

You don't need to restrict yourself to the use of a single prefix in IPv6.
Usually DR can allocate many prefixes to the RR.

Besides these prefixes are used for some time and then not needed any more.
I don't see any reason to be so frugal.

Regards,

Behcet

You could make the link unnumbered, but the WAN link could also be numbered.
If you refer to BBF TR-187, TR-177, TR-124i2  you can see that both
unnumbered and numbered  are considered valid scenarios.
PD-exclude is need in order to build the WAN numbered scenario with a single
prefix.

Roberta

PD-exclude allows to delegate a single prefix to the home network and than

delegated prefix and use it to number the point to point WAN link between
the requesting router (CPE) and the delegated router (BNG)

I still don't see why this is needed.

If you're using the /64 to number the link between the BNG and the CE
router, then the CE router already knows that the /64 is assigned to that
link via the O bit in the prefix information option in the RA.

If you're not using the /64 to number the link between the BNG and the CE,
then you can make the link unnumbered and you don't need to exclude
anything.

So...?
