Suggested answer: A, B, D

Explanation:

A) If BGP multipath is not configured, traffic may not be load-balanced across multiple paths. B. Without proper load-balancing policies, traffic distribution might not be optimal. D. Insufficient bandwidth between spine and leaf can lead to congestion and affect load balancing.

You are attempting to configure filter-based forwarding in your data center. All traffic from Host1 that is going to Host2 should be inspected by the data center firewall. You have verified that the traffic is being forwarded from router leaf L1's VRF-1 to its INSPECT-VRF. However, the traffic is not reaching service L2.

Referring to the exhibit, which two steps should you take to troubleshoot the problem? (choose two.)

A.
Examine the INSPECT-VRF.evpn 0 route table on L1 for a default route that will direct the traffic to L2.
