Concept Guide

In this RIOT scheme, whenever R1 tries to reach R2, the packet gets to P1 on VTEP 1 with VLAN 10 and gets routed out of P2 on VLAN
20. VTEP 1 sends an ARP request for R2 (10.1.2.1) through P2. This request gets VXLAN encapsulated at P3 and is sent out of P4.
Eventually, the native ARP request reaches R2.
R2 sends an ARP response that is VXLAN encapsulated at VTEP 2. This response reaches VTEP 1 on P4 with a VXLAN encapsulation. At
this point, the ARP response is de-capsulated at P4. The native ARP response egresses through P3 and re-enters through P2. The ARP is
then resolved pointing to P2.
After this ARP discovery is complete, the existing routing and VXLAN encapsulation mechanisms facilitate routing over VXLAN tunnels
between R1 and R2.
NOTE
: VXLAN feature is not supported in a stacking environment
Internal Loopback for VXLAN RIOT
The following topology shows how VXLAN RIOT can be achieved using an internal loopback port channel. Internal loopback port-channel is
formed by adding the free ports in the device as a member to the vxlan loopback port-channel. There is no need for non-vxlan loopback
port-channel in this scenario.
