Thanks Adam,
in fact, I'm already with 2 upstreams, each one with 2 links, I do
load balancing with them, announcing a /24 from one link to another
according to the traffic, these 2 existing ISPs have /24 filters.
I'm adding a new ISP with 3 links, and this 3rd ISP wants to change a
unique

Robert's response pretty much covers it all really.
If those 2 ISP's are advertising /24's out to the wider internet, your
screwed. Traffic will never come down via this new ISP.
The way to solve it, is to advertise the /24's as you already are, but get

Hi
If you advertise the /18 to one ISP (a) and the /24 to another ISP (b), you
will find that all your traffic will enter via the 2nd ISP (b) as it will be
the more specific routes in global BGP tables.
Is there a reason you wanted to use 64x /24's in the first place?
