Data Center Interconnect

Which two requirements are necessary to enable over-the-top DCI?

Choose two
  • A All leaf VTEPs in each network must be reachable.
  • B All spine loopbacks in each network must be reachable.
  • C EVPN route-types must be advertised to all spine devices.
  • D EVPN route-types must be advertised to all leaf devices.
Explanation

An over-the-top EVPN-VXLAN DCI requires reachability between leaf VTEPs so VXLAN-encapsulated traffic can traverse the inter-data-center underlay. EVPN route types must also be advertised to leaf devices, which use the EVPN control plane to learn remote MAC/IP and IP-prefix reachability. Spines provide transport and do not need to receive all EVPN routes for this purpose.
