> VXLAN routing allows hosts in different overlay networks (i.e.,
> different VNIs) to communicate with one another.
>
> Two popular routing models are asymmetric and symmetric routing.
>
> In asymmetric routing the ingress VTEP routes the packet into the
> correct VXLAN tunnel, whereas the egress VTEP only bridges the packet to
> the correct host. Therefore, packets in different directions use
> different VNIs - the target VNI.
>
> In symmetric routing both the ingress and egress VTEPs perform routing
> in the overlay network into / from the VXLAN tunnel. Packets in
> different directions use the same VNI - the L3 VNI. Different tenants
> (VRFs) use different L3 VNIs.
>
> Patch #1 adds a test for asymmetric routing. Patches #2-#3 reuse the
> topology and add test cases for ARP decapsulation and suppression.
>
> Patch #4 adds a test for symmetric routing.
Series applied, thanks!
