OSPF unnumbered No ping between Switch and Vm possible

I am trying OSPF Unnumberd and i have a VM (CentOs) and a Switch (Cumulus-Vx). When i try to ping from the Switch interface 1 to the Vm the Vm-Interface recieves the ICMP echo request but doesnt answer. When i look into the forward routing table i dont see the other router but with vtysh i see it. THe Target Router is the 10.1.0.1

Routing table:

[root@centosone vagrant]# netstat -rn

ICMP echo ignore all is set to 0. Any idea what could cause this? The Switch and the Vm have the Neighbor Status full. OSI layer 1 and 2 are correct

This error Occurs when you dont have the 10.0.* as Loopback adress on your Loopback-Adapter
