The city standardizes on symmetric IRB across the fabric for operational predictability. What is the strongest rationale?
Select an answer to reveal the explanation.
Short Explanation
Symmetric IRB is the 'same playbook on both benches' choice — policy and state look alike on each VTEP, which is easier to operate citywide. It does not delete Type-2s, force L2 hairpins, or abolish VNIs.
Full Explanation
Operators often prefer symmetric IRB because both VTEPs share a consistent L3 VNI/VRF encapsulation and routing behavior, simplifying policy, troubleshooting, and state expectations. It still relies on EVPN host/prefix signaling as designed; it does not eliminate Type-2, mandate L2-only spine hairpins, or remove VNIs from the data plane.
