Re: [address-policy-wg] 2006-05 New Policy Proposal (PI Assignment Size)

And, don't forget that you even can do multihoming without PI address space, by multihoming of PA assigment (if LIR permitted it).

It's nothing to do with your LIR. You can only do this if your secondary upstream agrees to it. Your LIR can shout and jump up and down and tell you not to do this, but they can't stop their competitor from leaking a prefix which they really shouldn't. Fortunately, most ISPs won't do this sort of thing. Nick
