Question
Can we interconnect different VRs of the same switch/stack through L2 domain?
Environment
  • EXOS
  • All Platforms
  • Virtual Router feature
Answer
 VRs should not be connected together through a Layer 2 domain. Since there is a single MAC address per switch in the EXOS, this same MAC address is used for all VRs. If two VRs on the same switch are connected through a Layer 2 domain, the intermediate Layer 2 switches learn the same MAC address of the switch on different ports, and may send traffic into the wrong VR.
 If you need to interconnect two VRs you can configure inter-VR routing or use external L3 router.
