[ppml] "Recommended Practices" procedure

Marla,

Currently we filter on the /32 boundry except for legacy /35s and critical
infrastructure.  

I don't disagree with you about providers filtering on the /48 boundry for
PI either.

But I don't see how anyone can defend allowing PI multihomers 1 slot
(/48) in the routing table, but not allowing PA multi-homers one slot
(/48) in the routing table.

Either de-aggregation is an acceptible solution to multi-homing, or it
isn't.  Whether the end-site uses a PI address or a PA address should make
no difference.

Secondly, when customers start to whine about wanting to slice up their
announcement to the global routing table the boundry may slip a bit.

___Jason

The good news about having an email address that is twice as long is that
it increases traffic on the Internet.

Then the document hopefully having a positive consensus of support can be taken to IETF for possibly being published as a IETF blessed document.

If the PI Policy goes through then I believe ONLY the /48's and more specific that FALL WITHIN the "Set aside block by ARIN", will have filters opened up for them to go through.  So if you dont receive an Allocation from the PI section, then you will still be filtered out at the /32.

Hopefully this would only be a short term solution.  I would hope this would motivate the Shim 6 or 8+8 groups to work faster towards a solution for multihoming.
