Re: Multihoming without AS

["Matthew Robinson" <]

I don't think that the providers need to be that much in cooperation as
probider B only needs to announce a /19 and statically point it at provider
A's router. I didn't want to do NAT as many customers don't like/want it. If
offered NAT they will go elsewhere!

Many thanks for your input
