A quick input:
Wihtout running BGP and playing with the BGP attributes(Local pref,Med and
AS pre-pending), it would be unwise to advertise the same route through two
different ISP's.
It would cause routing loops ,
as the world would have only one way to reach the main advertised services
like(Web,DNS,WEB) .Only ISP or company registered with IANA and
RIR(regional registration authority)would be preferred to pass the traffic
to the end host.
Cheers,
OK.
