Re: Multihoming without AS

Hi Matthew,

I have a working scenario, which is slightly different than yours by the fact
that the customer have a /28 (or /27) from each A and B providers.  The customer
is running NAT and also is balancing the traffic on both links (policy routing)
with floating default route to assure full backup of the links.  Having chunks
of /24 allocated to each customer, then there is no issue with the bunch of /24
announced, because each provider (ISP) will continue to advertise his /19 or
whatever.  Also, in your scenario, there is the assumption that provider A and B
are not competitors and they'll work together on behalf of the community :-)
Kind regards,
Corneliu Tanasa
