Correct answer & explanation
✓
MP-BGP with EVPN address family
MP-BGP with the EVPN address family (AFI 25 / SAFI 70) is the control-plane protocol used in VXLAN spine-leaf fabrics to advertise MAC/VTEP reachability, host routes, and integrated routing and bridging (IRB) information. This allows the spine to act as a route reflector, distributing EVPN type-2 (MAC/IP) and type-3 (IMET) routes to all leaf nodes, enabling efficient, loop-free overlay forwarding.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between the control-plane protocol (MP-BGP EVPN) and the data-plane encapsulation (VXLAN), so the trap here is that candidates confuse the underlay routing protocol (e.g., OSPF or eBGP IPv4 unicast) with the overlay control-plane protocol needed for EVPN route advertisement.
Detailed technical explanation
How to think about this question
Under the hood, MP-BGP for EVPN uses BGP UPDATE messages with MP_REACH_NLRI and MP_UNREACH_NLRI attributes to carry Network Layer Reachability Information (NLRI) encoded as EVPN routes (RFC 7432). In a spine-leaf topology, the spine is typically configured as a route reflector (using the 'neighbor route-reflector-client' command under the EVPN address family) to avoid a full mesh of iBGP sessions among leaf nodes. A real-world scenario where this matters is when deploying multi-tenancy: each VNI corresponds to a unique EVPN route target, allowing the spine to filter and distribute routes only to leaf nodes that host that tenant's VXLAN segment.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A network engineer at a university connects two campus buildings via a fibre link. Both routers run OSPF, but no adjacency forms — even though both routers can ping each other. The engineer finds one router is in area 0 and the other in area 1. OSPF adjacency requires matching area numbers, hello/dead timers, and network type. IP reachability alone is not enough.
