I have one WideIP with 3 Pools on Topology load balancing. In topology records i have Subnet1 ==> Pool1 Weigh 10 Subnet1 ==> Pool2 weight 5 Subnet1 ==> Pool3 weight 1 Now if the Pool1 is down or disabled it should failover to Pool2, that is how it was in 3DNS and 9.x but in 10.x and above it doesnt seem to be working. Anyone faced this issue?

Are you using longest match for topology? I've encountered this issue before which caused unexpected answers to be returned: http://support.f5.com/kb/en-us/solutions/public/14000/700/sol14794.html
