Exam JN0-683 Topic 1 Question 34 Discussion

Actual exam question for Juniper's JN0-683 exam
Question #: 34
Topic #: 1
You are asked to build redundant gateways in your EVPN-VXLAN environment, but you must conserve address space because these gateways must span across seven PEs.
What should you implement on the PEs to satisfy these requirements?

Suggested Answer: C Vote an answer

In an EVPN-VXLAN environment, when you need redundant gateways across multiple PEs (for hosts in the same VLAN/VRF), you want all PEs to present a single logical gateway IP to the hosts.
This is achieved using anycast IRB:
Same IP address on all PEs → ensures hosts have a single default gateway.
Same MAC address on all PEs → ensures traffic is correctly forwarded to the closest PE without ARP conflicts.
This design conserves IP address space because you don't need a unique gateway IP for each PE.
