[c-nsp] PBR two default gateway

You need to match the traffic of the source and destination, in an ACL in the route-map. 
Yours probably being :

ACL-PBR-SUBNET-A
Permit XX.xx.xx.xx 0.0.0.255 any

route-map FOO permit 10
match ip address ACL-PBR-SUBNET-A
 set ip next-hop x.x.x.x

then "debug ip policy" to watch it firing, or not firing (if this is not in production yet)

You must test from behind the router - from a host on the subnet )  - as self-generated traffic requires another type of PBR (local policy)

I have router with two subnet A & B connected on related physical interface. and we have two ISP link so i want to send subnet A to ISP-A and subnet B to ISP-B.

is it enough if i do this or do i need to use match interface F1/1?
Because i want to do whatever coming from my source interface go to ISP-A and rest will use ip route 0.0.0.0 0.0.0.0 ISP-B

!
interface FastEthernet1/1
 description subnet-A
 ip address x.x.x.x 255.255.255.0
 ip policy route-map FOO
!
!
route-map FOO permit 10
 set ip next-hop x.x.x.x
!
