Neutron/L3 High Availability VRRP
DVR (Ditributed Virtual Routing ) aims to isolate the failure domain of the traditional network node and to optimize network traffic by eliminating the centralized L3 agent shown above. It does that by moving most of the routing previously performed on the network node to the compute nodes.

Thanks for your replay. I am planing to deploy large scale openstack cluster with HA, but I am not sure if i should use ovs or linux bridge. Can you give me a suggestion on this, which driver I need to use in case of large scale deployment.

I don't follow your question. What kind of driver you mean ?

I am trying to implement openstack cluster. But confused whether I should use OVS or linux bridge for neutron. Can you give an opinion about this, when deploying a large scale openstack cluster. Which will be better, OVS or linux bridge?

I have experience only with OVS on RDO deployments ( with HA Controllers in particular )

In simplest way. Distributed Virtual Router (DVR) functionality use Virtual Router Redundancy Protocol (VRRP) to elect master router.
