   A company is deploying a VXLAN fabric with asymmetric IRB on Dell SONiC. They have two VTEPs: VTEP-A and VTEP-B. A host connected to VTEP-A in VLAN 10 needs to communicate with a host connected to VTEP-B in VLAN 20. Both VLANs are mapped to different VNIs. How does asymmetric IRB handle this east-west traffic?

   • AVTEP-A routes the traffic to VTEP-B, which then bridges it to the destination host.
   • BVTEP-A performs both bridging and routing for the traffic, then forwards it to VTEP-B over VXLAN.
   • CA central gateway router performs routing, and both VTEPs only bridge traffic.
   • DVTEP-B performs routing for the traffic, while VTEP-A only bridges it.
