Question

Planners must choose how a civic application spans two DCs: keep the same L2 segment stretched, or interconnect only at L3. In EVPN-VXLAN DCI terms, which statement is correct?

Accepted Answer

Use Type-2/L2 VNI stretch when the same broadcast domain must span sites, or Type-5 L3 DCI when only IP prefixes should interconnect — Need the same Ethernet neighborhood in both buildings? That is L2 stretch with Type-2 style MAC signaling. Just need IP between VRFs? Type-5 L3 DCI keeps the blast radius smaller. Pick the route type that matches the real requirement.

Answer

Type-5 routes always stretch broadcast domains; Type-2 routes are only used for underlay loopbacks

Answer

Type-2 and Type-5 are interchangeable for every DCI requirement with identical blast-radius outcomes

Answer

L3 DCI requires disabling EVPN and configuring only static VXLAN tunnels between borders
