> Virtual routers are assigned name servers via the kernel arguments. These name servers are also presented via DHCP to guest VMs - but the virtual router prepends these name servers with it's own guest IP. This allows the virtual router to act as a name resolver for guest VMs.
> With redundant virtual routers, the router's guest IP is not the same as the virtual gateway IP. This means that after a failover or a network restart, guest VMs will not be able to find the name server assigned via DHCP and this causes delays whenever name resolution is needed.
> Redundant virtual routers should provide the guest gateway IP to guest VMs instead of their own guest IP. This will allow name resolver functionality to continue after failover or network restart events.
