Which statement describes proper packet processing of layer 3 traffic in an NSX for vSphere
topology?
A.
All packets are processed by the distributed router. No packets are processed by the Logical
Router Control VM.
B.
Only packets requiring routing to another VM on the same host are processed by the distributed
router. Other packets are processed by the Logical Router Control VM.
C.
Only packets requiring routing to another VM on a different host are processed by the
distributed router. Other packets are processed by the Logical Router Control VM.
D.
All packets requiring routing are processed by performing a lookup in the Logical Router
Control VM and then forwarded.
Guessing B
I believe it’s “A”, all packets are processed by the distributed router…or DLR.
See this blog:
https://blogs.vmware.com/networkvirtualization/2013/11/distributed-virtual-and-physical-routing-in-vmware-nsx-for-vsphere.html
“The DLR is unique because it enables each vSphere hypervisor host to perform L3 routing between virtual and physical subnets in the kernel at line rate. “
The logical Router control VM is in the control plane not data plane. Any answers that imply that packets are processed by the control VM is incorrect.
So only A is the correct answer.
