The answer is that all VTEPs must share a common anycast IP address for the default gateway. This is a core requirement in a centralized anycast gateway VXLAN EVPN design because it enables any VTEP in the fabric to act as the first-hop router for locally attached hosts, eliminating the need for a dedicated external gateway device. By configuring the same anycast IP and MAC address on each VTEP’s VLAN interface, the network achieves seamless east-west traffic forwarding and optimal path selection, as the anycast gateway is advertised via EVPN Type-2 routes. On the Cisco DCCOR 350-601 exam, this concept tests your understanding of how centralized anycast gateways differ from distributed designs—a common trap is assuming a separate gateway device is still required. Remember the key distinction: in a centralized design, the anycast gateway lives on every VTEP, not on a single router. Memory tip: “One IP for all VTEPs, any VTEP can route.”

Correct answer & explanation
✓
All VTEPs share a common anycast IP address for the default gateway.
In a centralized anycast gateway VXLAN EVPN design, all VTEPs share a common anycast IP address and MAC address for the default gateway. This allows any VTEP to serve as the first-hop router for hosts, enabling optimal east-west traffic forwarding without requiring a separate gateway device. The anycast IP is configured on each VTEP's VLAN interface, and the same IP/MAC is advertised via EVPN Type-2 routes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Each VTEP has a unique anycast IP address.
Why it's wrong here
Anycast means the IP is shared, not unique.
✓
All VTEPs share a common anycast IP address for the default gateway.
Why this is correct
This is the definition of centralized anycast gateway.
Related concept
Read the scenario before looking for a memorised answer.
✗
The anycast gateway is configured on the spine switches.
Why it's wrong here
The anycast gateway is typically on leaf switches.
✗
The route reflector is an external BGP speaker.
Why it's wrong here
Route reflectors are often internal switches.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that the anycast gateway is configured on spine switches or that each VTEP uses a unique anycast IP, when in fact the shared anycast IP/MAC on leaf VTEPs is the defining requirement.
Detailed technical explanation
How to think about this question
The anycast gateway uses the same IP and MAC on all leaf VTEPs, relying on the underlay routing (e.g., OSPF or IS-IS) to direct traffic to the nearest VTEP. This design eliminates the need for a default gateway in the overlay, as each VTEP locally responds to ARP requests for the gateway IP. In real-world deployments, this reduces latency for inter-subnet traffic and simplifies failover, as hosts do not need to learn a new gateway MAC when a VTEP fails.

→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 help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
