InterNetwork VNF access does not work when networks are associated to EVPN

Created the topology from openstack as per below commands.....

I can see that VNF of same network are reachable .
But, when we try to access the VNF from Network1 to Network2 they are not working.

Example : ping from 11.0.0.2 to 12.0.0.2 does not work.
