Communication between two route domain not happening

Hi All,

I have two route domains configured o the BIG ip system. RD1 is configured as parent for RD2. Strick isolation is enabled for both route domains.The default gateway for both route domains are internet routers on different vlans. There are two different global forwarders for RD1 and RD2 seperately.

Now there is no comunication is happening from the server connected on RD1 to the destination server connected on RD2.

The routes on F5 looks like below.

10.10.43.0%2/24         10.10.43.0%2/24    interface  /Common/F5_Infra_Svcs_APP  connected

Default_Route_RD1    default%1           gw         10.11.22.254%1       static

Traffic is taking the default route rather taking the directly connected route on RD2. Not sure what is the problem. Theoretically it should take the connected route on RD2 and go out but unfortunately not happening here.

Any clues?
