Two static routes to the same destination not working

[ramyacruz]

I am trying to configure a 3850 switch to be able to route to destinations 192.168.XXX.21 and 192.168.YYY.21 via two routers. I have sub-interface between the router and the switch for connectivity. RT1 is 10.20.XX.1 and RT2 is 10.20.YY.1. The problem I am currently having is that I am able to reach only one destination when source it from 10.20.XX.5 and the other when I source it from 10.20.YY.5, but not both. Both routers have connectivity to both destination subnets.

ip route 192.168.XXX.0 255.255.255.0 10.20.XX.1
ip route 192.168.XXX.0 255.255.255.0 10.20.YY.1
ip route 192.168.YYY.0 255.255.255.0 10.20.XX.1
ip route 192.168.YYY.0 255.255.255.0 10.20.YY.1

Sounds like a return-path error. Check the other side to see if everything is routed correctly.

The other side is routed correctly and working fine.
