Hello Pedro, Neutron has some (limited) capabilities for injecting static routes into instances. You can try whether the subnet's host_routes attribute [1] can satisfy your requirement. Routes can however be specified only in the form destination CIDR/next hop. Note: the host_routes option leverages DHCP option 121 in the reference implementation and therefore requires DHCP on network interfaces.
