I want to load share traffic for my two network segments. I have two routers with each internet circuit running BGP with two different ISPs(ISP- A & ISP-B). Also running IBGP between two routers. Since i have two /24 segments(not provided by ISP) so i want one segment to prefer via ISP A & other segment to prefer via ISP B. I have configured EBGP & IBGP and configured AS-path prepend but i see some asymmetric behaviour. Source traffic which prefer via ISP -A is going via it but incoming traffic is via ISP-B.
Pls suggest how this asymmetric behaviour could be fixed.
