Re: A new spin on multihoming: multihoming classes.
I have no desire to change existing BGP system - it will be needed to keep the
aggregated direct routing framework in place. The key point I was trying to
make was decoupling of an alternative BGP cache from the routing
From my reading of
it becomes clear that multihoming is already a major degradation issue for the
Ipv4 network based on current BGP models. I especially note the growth in the
longer prefixes (/24).
