We have found that about 5% of sites are connected to 2 ISPs but do not use BGP. They use two different sets of IP addresses and point default to one of the two ISPs. The return traffic will of course go to them via one of the two ISPs, but if you have anti-spoofing filters set up or try to set it up now, you will break their outgoing traffic.
They need better routers which can source route, then absolutely nothing will break (and their return traffic wont be taking suboptimal assymetric paths). -Dan
