Some of it is at http://www.netaxs.com/~freedman/multi.html. I'll see about
making it better and simpler - and will add some simple configs that are
somewhat bit more idiot-proof.
And it has to be clear that if:
a) Your providers will configure their networks to only announce you if
your line is up (+/- any damping), and
b) You believe that a load-balanced defaul route with 'ip route-cache' on
will do good data delivery out from your network
That BGP does not need to be involved at all for the multi-homed.
