Ok, you cannot reach vlan.10 via me0.0. I expect that you via the management network (10.255.128.0/17) connected to me0.0 has a static route for 10.255.127.230/32 towards 10.255.254.1. Having a /32 route on a vlan interface does not make much sense :-)
This is not how you should do inband management. You should place the RVI (vlan.10) in your management vlan and define an IP in that subnet. I guess this is 10.255.128.0/17... So move the me0.0 IP to vlan.10 and change to different vlan if it makes sense.
But! May I guess? You are trying to do inband management on your EX3300 virtual-chassis to avoid loosing management access when the routing-engine is moved to another switch.
If i'm correct you can instead look into using the virtual management interface (vme) instead. This features provides a shared management IP for the virtual-chassis which moves to the active routing-engine. You just need to cable all management-interfaces to your management-infrastructure.
