Exhibit.

Referring to the configuration shown in the exhibit, assume that there is no external router present, and that the configuration is fabric-only.

Which two statements are true about the example configuration? (Choose two.)

A.
VNI 10006 is assigned to vlan 800 (irb.800).
Answers
A.
VNI 10006 is assigned to vlan 800 (irb.800).
B.
Devices in irb.400 (vlan 400) are not able to communicate directly with devices in routing instance Customer A.
Answers
B.
Devices in irb.400 (vlan 400) are not able to communicate directly with devices in routing instance Customer A.
C.
Devices in routing instance Customer A are able to communicate with devices in routing instance Customer B
Answers
C.
Devices in routing instance Customer A are able to communicate with devices in routing instance Customer B
D.
Devices in irb.400 (vlan 400) and irb.800 (vlan 800) are able to communicate over the fabric.
Answers
D.
Devices in irb.400 (vlan 400) and irb.800 (vlan 800) are able to communicate over the fabric.
Suggested answer: B, D

Explanation:

Understanding the Configuration:

The exhibit shows configurations for two VRFs (Customer_A and Customer_B) with specific VLANs and VNIs assigned. Each VRF has interfaces (IRBs) associated with particular VLANs.

Communication Between VLANs and Routing Instances:

Option B: VLAN 400 (irb.400) is part of Customer_B, and there is no direct connection or routing between Customer_A and Customer_B in the configuration provided. Therefore, devices in irb.400 cannot communicate directly with devices in the Customer_A routing instance.

Option D: Since irb.400 (VLAN 400) and irb.800 (VLAN 800) are part of the same routing instance (Customer_B), they can communicate over the fabric using VXLAN encapsulation.

Conclusion:

Option B: Correct---There is no direct communication between devices in irb.400 (Customer_B) and routing instance Customer_A.

Option D: Correct---Devices in VLAN 400 and VLAN 800 can communicate within the Customer_B routing instance over the fabric.
