350-601 Network Practice Question
Which two VXLAN control plane options are supported on Cisco Nexus 9000 switches? (Choose two.)
⚠ Common exam trap
Cisco often tests the distinction between VXLAN control plane options and other overlay technologies (like OTV) or configuration methods (like static tunnels), leading candidates to confuse supported control planes with unrelated features.

Correct answer & explanation
✓
Multicast
VXLAN on Cisco Nexus 9000 switches supports both multicast-based control plane (using IGMP/PIM to flood BUM traffic) and MP-BGP EVPN (RFC 7432) as the control plane for distributing MAC/VTEP reachability. Multicast is the traditional method for handling BUM traffic in VXLAN fabrics, while MP-BGP EVPN provides a more scalable, standards-based control plane with host route advertisement and multi-tenancy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Multicast
Why this is correct
Traditional VXLAN uses multicast for BUM traffic and MAC learning.
- ✗
OTV
Why it's wrong here
OTV is a different overlay technology, not VXLAN.
- ✗
Static VXLAN tunnel
Why it's wrong here
Not a control plane; manual tunnel setup.
- ✗
OpenFlow
Why it's wrong here
Not used for VXLAN control plane on Nexus.
- ✓
MP-BGP EVPN
Why this is correct
Standard control plane for VXLAN.
