QuestionQ40

DCI And 7750 SR interoperability

Which of these statements about the gateway-less data center interconnect solution is false?

  • A The IP addresses of the leaf routers need to be re-distributed into the WAN.
  • B The EVPN overlay is transparently carried over the WAN network.
  • C The leaf routers are able to establish a full mesh of VXLAN tunnels across the WAN.
  • D The data center gateway routers maintain a MP-BGP EVPN peering with the data center route reflector.
Explanation

A gateway-less DCI design carries the EVPN/VXLAN overlay directly across the WAN between data center leaf routers. The WAN must route the leaf-router/VTEP addresses, while the leaf routers establish the inter-site VXLAN tunnels. Because this design does not use data center gateway routers as EVPN control-plane endpoints, such gateways do not maintain MP-BGP EVPN peerings with the data center route reflector.
