QuestionQ127

Network

An engineer needs to implement a VXLAN-based data-center interconnect. The service provider supplies long-distance IP transport that supports a maximum MTU of 1554 bytes but does not support outbound traffic replication. Which action is required to build the data-center interconnect?

  • A Announce host reachability over BGP.
  • B Create an IP access list and associate it with VNI to replicate traffic to remote VTEPs.
  • C Configure a route map to associate the IPs of the remote VTEPs.
  • D Implement BGP EVPN ingress replication.
Explanation

BGP EVPN ingress replication provides head-end replication of broadcast, unknown-unicast, and multicast traffic as separate unicast VXLAN packets to discovered remote VTEPs. It is the appropriate replication method when the IP transport does not provide multicast or outbound replication. Cisco documents that BGP EVPN ingress replication uses IMET routes to discover remote VTEPs and establish BUM tunnels.
