Network Design

An engineer needs to design a disaster-recovery solution for a Cisco ACI Multi-Site network. A requirement is for applications to maintain seamless IP addressing across sites. The solution must also be highly resilient and provide Layer 2 adjacency. Which design satisfies these requirements?

  • A localized bridge domain, subnet, and EPGstretched Layer 2 broadcast domain
  • B stretched bridge domain with local subnetstretched Layer 2 broadcast domain
  • C localized bridge domain with local subnetlocalized Layer 2 broadcast flooding
  • D stretched bridge domain, subnet, and EPGlocalized Layer 2 broadcast flooding
Explanation

A stretched bridge domain, subnet, and EPG provides a common Layer 2 domain and consistent endpoint addressing and policy across sites. Keeping Layer 2 broadcast flooding localized reduces inter-site flooding overhead while supporting inter-site IP mobility for disaster recovery. Cisco identifies this stretched-bridge-domain design with localized flooding as a disaster-recovery use case.
