Ops proposes naively stretching the same IP fabric underlay ASN across two city data centers over the WAN. What boundary concern should be raised?
Select an answer to reveal the explanation.
Short Explanation
Gluing two city fabrics into one underlay ASN "just because" is like knocking down the firewall between two buildings and hoping for the best. Interconnect separate fabrics on purpose; do not accidentally build one giant underlay.
Full Explanation
Geographic data centers are ordinarily separate IP fabrics interconnected with a deliberate DCI model. Naively extending one underlay ASN across cities can create large failure domains, awkward routing policy, and operational coupling without providing a clean overlay stretch design. Interconnect the fabrics; do not assume one fabric underlay is the default across sites.
