[NETVIRT-1034] OptimisticLockFailedException : Conflicting modification for path id=515001951165718665375538295133659fa:16:3e:a4:3a:03

with review https://git.opendaylight.org/gerrit/#/c/63422/, there is an issue with InterSubnet Routing Intra-DC. Even the issue appears when trying to access the first VM between DHCP Server and the VM.

Here is the configuration used:

openstack router create router
openstack network create N1
openstack subnet create --network N1 SUB1 --subnet-range 10.10.10.0/24  
openstack router add subnet router SUB1
neutron port-create N1 --name=port1
nova boot --image cirros-0.3.4-x86_64-uec --flavor m1.tiny --nic port-id=3ce33b76-9c38-46f9-8f24-da3e08264886 VM1
