Actual exam question for Juniper's JN0-683 exam

Topic #: 3
[All JN0-683 Questions]

Exhibit.

You are deploying a VXLAN overlay with EVPN as the control plane in an ERB architecture.

Referring to the exhibit, which three statements are correct about where the VXLAN gateways will be placed? (Choose three.)

Show Suggested Answer Hide Answer
Suggested Answer: B, C, E

Understanding ERB Architecture:

ERB (Edge Routed Bridging) architecture is a network design where the routing occurs at the edge (leaf devices) rather than in the spine devices. In a VXLAN overlay network with EVPN as the control plane, leaf devices typically act as both Layer 2 (L2) and Layer 3 (L3) VXLAN gateways.

Placement of VXLAN Gateways:

Option B: All leaf devices will have L2 VXLAN gateways to handle the bridging of VLAN traffic into VXLAN tunnels.

Option C: All leaf devices will also have L3 VXLAN gateways to route traffic between different VXLAN segments (VNIs) and external networks.

Option E: Spine devices in an ERB architecture generally do not function as VXLAN gateways. They primarily focus on forwarding traffic between leaf nodes and do not handle VXLAN encapsulation/decapsulation.

Conclusion:

Option B: Correct---All leaf devices will have L2 VXLAN gateways.

Option C: Correct---All leaf devices will have L3 VXLAN gateways.

Option E: Correct---Spine devices will not act as VXLAN gateways

Haha, looks like we've got some VXLAN magic happening here! I'm going to guess B, C, and D. Gotta love those leaf devices, they're the real MVPs when it comes to VXLAN gateways. The spine devices can just sit back and enjoy the show.

Yeah, the leaf devices really do all the heavy lifting in this setup. They're essential for making the VXLAN magic happen.

I think you're right! Leaf devices are definitely the stars of the show when it comes to VXLAN gateways.

I'm not sure about option B, I think only the border and leaf devices will have L2 VXLAN gateways.

This is a tricky one, but I'll go with B, C, and D. The leaf devices need to do the heavy lifting with both L2 and L3 VXLAN gateways, while the spine devices can just focus on routing. Sounds like a job for the leaf nodes!

I'm going with B and C. All leaf devices need both L2 and L3 VXLAN gateways to handle the overlay traffic. The spine devices are just for routing, no VXLAN needed there.

That's correct. The spine devices are just for routing, so they won't have VXLAN gateways.

Hmm, I think B and D are the correct answers. The leaf devices need to handle the L2 VXLAN gateway, and the border and leaf devices should have the L3 VXLAN gateways.

I think D is also correct because border and leaf devices will have L3 VXLAN gateways.
