[address-policy-wg] PA Assignment questions

And since this is a workaround, just like a company stretching the truth about their IP requirements when applying for a PI Space to get a full /24, surely a LIR should be allowed to create inetnum's for a /24 when they also need to create a /24 route object.

please have a look at

http://www.ripe.net/ripe/policies/proposals/2006-05.html

and the discussions on the ap-wg list (i think) about it in the 
mailinglist archive if you don't read the list on a regular basis.

It's partially about your problem here.
It is indeed considered a problem by some other people, too.
Although the current thinking by most involved in the policy process 
seems to be that it's weired that you need PI space and your own routing 
policy for two or three boxes (or so) in the first place.

In any ways, it's probably still a design problem. Why did you design a 
network with multiple locations and no connection between them as a 
normal network architect would do?
It's probably none of our business here how you design your network, but 
that is considered a fail anyways :-)

If you really have independent locations, you need independent 
ressources, multiple LIRs probably or multiple PI Assignments.
It's a really bad habbit to slit up PA Allocations and might not work 
out for you in all cases, you need workarounds like Tunnels between the 
locations and a site announcing the aggregate so you don't run into the 
PA Filters ... and so on ...

But again, i don't really see the problem, i'm afraid. Probably some 
other people on the list can.

P.S.: Don't think too much about address conservation. It's overrated, 
we have IPv6 now :-)
