Description bkopilov 2014-10-23 08:15:14 UTC
Description of problem:
Topolgy : multi-node setup with neutron 
Rhel 6.5 with rhos5 . 

Router configured in admin tenant

the dhcp lease time was 120 seconds in neutron.conf

After dhcp time expires the virtual machine address updated but without default route.
Due to that we can not access from and to virtual machine
