Hi ,
Could anyone please guide me in which case should i use a separate neutron node ,since i am doing a POC and i have to decide between Neutron and Legacy Networking ,and how a separate Node is helpful when it adds to overheads of communication between the nodes .
To be honest I almost forgot all what I knew about nova-networking.

is devoted to Juno. However, VRRP && DVR work for Kilo and Liberty as well.
Since Juno release you are not forced to have single point of failure for L3 routing as Network Node.
Due to DVR North-South traffic may be distributed across Compute Nodes.See

DVR distributes East-West traffic via virtual routers running on compute nodes. Also virtual routers on compute nodes handle North-South floating IP traffic locally for VM running on the same node. However if floating IP is not in use, VM originated external SNAT traffic is still handled centrally by virtual router in controller/network node.
HA L3 Agent provides virtual router HA by VRRP. A virtual gateway IP is always available from one of controller/network node.
