I have 5 routers named R0 to R4. R2 is doing static routing with R0 & R3. R0 is ASBR for area 0, R3 is ASBR for area 1 & R1 is ABR for area 0 & 1. R4 is the simple router which is participating in area 1. A route 126.96.36.199 which is the loopback of router R2 and redistributed from the ASBRs. OSPF cost fo link R3-R4 has been changed to 1000. Now the 188.8.131.52 route is preferred via R1, From R1 it should perform the load balancing but it is not performing. On R1 I am getting 184.108.40.206 route from the both ASBRs but it always follow the R3 path. But If I trace from r1 to 220.127.116.11 load balancing is actually happening but not when the packet comes from R4.
After that I disable the CEF from the R1 and no ip route-cache command is added to serial 0/0 & serial 0/1. After that load balancing starts from R1 when traffic comes form R4. I am not able to understand the reason for that.
