Answers
C.

D.
Use IRB interfaces with different IP addresses and the same VGA.
Answers
D.
Use IRB interfaces with different IP addresses and the same VGA.
Suggested answer: C

Explanation:

Redundant Gateways in EVPN-VXLAN:

In an EVPN-VXLAN environment, providing redundant gateway functionality typically involves the use of Anycast Gateway. This allows multiple PEs (Provider Edge devices) to use the same IP address and MAC address for the gateway, enabling seamless failover and redundancy without IP conflicts.

Conserving Address Space:

Using the same IP address across multiple PEs conserves address space because only one IP address is needed for the gateway function, regardless of the number of PEs. The shared MAC address ensures that ARP resolution and forwarding behavior are consistent across all the PEs.

Conclusion:

Option C: Correct---Using IRB interfaces with the same IP and MAC address across all PEs satisfies the need for redundancy while conserving address space.

Options A, B, and D introduce unnecessary complexity or do not fully utilize the efficient Anycast Gateway approach, which is best practice for conserving IP space and providing redundancy.
