Question #: 17
Topic #: 2

Exhibit.

Referring to the exhibit, Host1 (10.1.1.1) is failing to communicate with Host2 (10.1.2.1) in a data center that uses an ERB architecture. What do you determine from the output?

AThe traffic is failing because load balancing is not configured correctly.

BThe traffic is entering the VXLAN tunnel.

CHost1 and Host2 are directly connected to leaf1.

DThe irb.20 interface is not configured on leaf1.

Show Suggested Answer

Suggested Answer: B

Understanding the Problem:

Host1 (10.1.1.1) is failing to communicate with Host2 (10.1.2.1) within an EVPN-VXLAN environment using ERB architecture.

Analysis of the Exhibit:

The provided output includes information from the show route forwarding-table matching command for IP 10.1.2.1. The next hop is shown as vtep.32769, which indicates that the traffic destined for 10.1.2.1 is being forwarded into the VXLAN tunnel with the correct VTEP (VXLAN Tunnel Endpoint).

Conclusion:

Option B: Correct---The traffic from Host1 is entering the VXLAN tunnel, as evidenced by the next hop pointing to a VTEP. However, the issue could lie elsewhere, possibly with the remote VTEP, routing configurations, or the receiving leaf/spine devices.

I believe Host1 and Host2 are directly connected to leaf1.

I think the issue is with the VXLAN tunnel.

Hmm, looks like the issue is with the irb.20 interface not being configured on leaf1. I'm guessing that's the key to getting Host1 and Host2 to communicate properly.
