Intervlan ospf?

Hey guys im completely stumped im doing some labbing and just cant seem to make this work. I have a layer 3 switch connected to a router and just cant get them to have an ospf adjacency.any advice will be very much appreciated. Is routing using an int vlan even possible?

Switch

Vlan 51 Name test

Int vlan 51 Ip add 10.10.51.1 255.255.255.240 No shut

Router ospf 456 Network 10.10.51.0 0.0.0.15 area 51 Default information originate

Int g0/0 Switchport trunk encapsulated dot1q Switchport mode trunk Switchport trunk allowed vlan 51

Also tried

Int g0/0 No switchport

Router

Int g0/0.51 Encapsulation dot1q 51 Ip address 10.10.51.2 255.255.255.240

Int. G0/0 No shut

Router ospf 456 Router id 50.1.1.2 Network 10.10.51.0 0.0.0.15 area 51

I’m not sure if this is doable or I’ve read something about ethernet virtual circuit (evc) if that could help me?
