Unable to Ping Tier 0 Gateway From Segment VM

So I've got one physical adapter connected to a layer 3 switch as a trunk port. The host and edge transport nodes are both configured with a transport vlan of 10 and the layer 3 switch has an svi of 10.10.1.1/24 on vlan 10. This is the tep ip gateway and the tunnel status is showing up.There is also an svi for vlan 2 that is setup and has an ip address of 10.10.2.1/24. This forms an adjaceny with the tier 0 gateway and the state is showing full. I have a segment created for a test vm with a vlan id of 3 and it's in the overlay transport zone. Its ip is 10.10.3.1/24 and there is also a vlan created for it on the layer 3 switch with the svi 10.10.3.1. The MTU is set to 1600 everywhere and there's no firewalls blocking any routing. I'm still unable to route from the test vm to the physical network and am having issues with north/south bound connectivity. It can ping the tier 0 gateway, but that's it. The SVIs and interfaces are using OSPF in area 0. Any help would be greatly appreciated.

 I have a segment created for a test vm with a vlan id of 3 and it's in the overlay transport zone. Its ip is 10.10.3.1/24 and there is also a vlan created for it on the layer 3 switches with the svi 10.10.3.1. 

I'm a bit confused with this statement. Are you using overlay-based segments or VLAN-backed segments ? Ensure you are using the right segments and transport zone and let OSPF  route workload segments via T0 ( In your case OSPF adjacencies are already up) so as long as T1&T0 routes are advertised, you must see workload routes in Layer 3 switch.
