Version: 4.0.1.0-50

Topo: host1 = 'root@10.204.216.95'
host2 = 'root@10.204.216.96'
host3 = 'root@10.204.216.97'
host4 = 'root@10.204.216.98'
host5 = 'root@10.204.216.99'
host6 = 'root@10.204.216.103'
host7 = 'root@10.204.216.160'

ext_routers = [('blr-mx1', '10.10.10.101')]
env.roledefs = {
    'all': [host1, host2, host3, host4, host5, host6, host7],
    'contrail-controller': [host6, host2, host1],
    'contrail-analytics': [host6, host2, host1],
    'contrail-analyticsdb': [host6, host2, host1],
    'openstack': [host6, host2, host1],
    'contrail-compute': [host3, host4, host5],
    'contrail-lb': [host7],
    'build': [host_build]
}

I see that the DM config on mx box is removed after I extend the VN and try to ping to the lo0 ip from my VM.
