RE: A proposal for reducing routes due to multihoming

I think you miss the whole reason that we want multihoming. We want higher reliability. If you use one block for both providers say Sprint and MCI then when Fortworth takes another fiber cut (happens every few months) Sprint will bitbucket traffic that arrives inside their network for my system. Or if I see that one provider is flapping nationwide then I withdraw my routes and down the interface to that provider. That is how I see higher reliability.
