bgp + pbr help

I have 4 bgp peers 3 isp and 1 cdn. 3 isp sends just default routs. CDN advertises 400 prefixes. I have to do policy routing with subnets src ips going to each of isp and all received routes desitnation going to cdn but as soon as i do policy routing rules they failed to go to cdn peer. Moreover I want to redistribute received bgp routes to other bgp peers not shown in picture just redistribute bgp routes.
