This 350-601 practice question tests your understanding of network. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
In a VXLAN EVPN fabric, which protocol is used to exchange MAC and IP address reachability information among VTEPs?
BGP
BGP EVPN is the standard control plane for VXLAN.
IS-IS
Why wrong: IS-IS is also an underlay protocol, not used for EVPN.
EIGRP
Why wrong: EIGRP is a Cisco proprietary underlay protocol, not for EVPN.
OSPF
Why wrong: OSPF is a link-state routing protocol for underlay, not for MAC/IP routes.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
BGP
In a VXLAN EVPN fabric, BGP (Border Gateway Protocol) is used as the control plane protocol to exchange MAC and IP address reachability information among VTEPs. Specifically, MP-BGP (Multiprotocol BGP) with EVPN address family (AFI L2VPN / SAFI EVPN) carries Type-2 routes (MAC/IP advertisement) to distribute host reachability across the overlay network, enabling efficient MAC learning and ARP suppression.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

IS-IS
Why it's wrong here
IS-IS is also an underlay protocol, not used for EVPN.
EIGRP
Why it's wrong here
EIGRP is a Cisco proprietary underlay protocol, not for EVPN.
OSPF
Why it's wrong here
OSPF is a link-state routing protocol for underlay, not for MAC/IP routes.
Common exam traps
Cisco often tests the distinction between underlay routing protocols (OSPF, IS-IS, EIGRP) and the overlay control plane (MP-BGP EVPN), leading candidates to mistakenly select an IGP that handles only underlay IP reachability rather than the protocol that actually exchanges MAC/IP information in the overlay.
Detailed technical explanation
MP-BGP for EVPN uses BGP EVPN routes (RFC 7432) to advertise MAC/IP bindings, with Type-2 routes carrying both MAC and IP addresses, enabling distributed anycast gateway and ARP suppression. Under the hood, VTEPs establish BGP sessions (eBGP or iBGP) over the underlay network, and the EVPN control plane eliminates the need for data-plane flooding for unknown unicast, significantly reducing broadcast traffic in large fabrics. In real-world deployments, BGP route reflectors are often used to scale the control plane across hundreds of VTEPs.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
