Municipal IPv6 tenants need host advertisements in the EVPN-VXLAN control plane alongside IPv4. What design awareness is required?
Select an answer to reveal the explanation.
Short Explanation
Dual-stack civic apps need the overlay phone book to speak both IPv4 and IPv6 host bindings—not just one. Turning on IPv6 underlay loopbacks is about reaching VTEPs, not auto-publishing tenant GUAs. EVPN is not an IPv4-only club that forces you back to GRE.
Full Explanation
EVPN Type-2 MAC/IP advertisement can include IPv4 and IPv6 host addresses when the implementation and configuration support those families for the tenant. Dual-stack municipal workloads therefore require control-plane and IRB/VRF settings that actually advertise and import the needed address families. Underlay IPv6 reachability to VTEPs is separate from tenant host route advertisement. Claiming EVPN is IPv4-only or that GRE is mandatory for IPv6 tenants is incorrect for modern EVPN-VXLAN designs.
