Hello All,
              Is there any enterprise network device that can fully
replace neutron network node?
with all the features like tunneling,Functionality of separate network
namespace,ie  dhcp/router,Redundancy,Firewall rules for each
tenant,VLAN isolation for each ip namespace.

i am basically looking for a solution to replace  a generic linux
network node with a device designed to be a network device.

or

 Can SDN  solution like Plumgrid/Cisco Nexus1000v
[https://wiki.openstack.org/wiki/Neutron#Plugins] completely replace
linux network node with an enterprise switch,or does this still use
network node as datapath?

Thanks
