FBGP is only required to route most routing information to external devices outside the fabric.
Suggested answer: A, B

Explanation:

BGP in IP Fabric:

In an IP fabric, Border Gateway Protocol (BGP) is used to manage the routing between leaf and spine devices. Each device can have the same or different Autonomous System (AS) numbers depending on the network design.

Multipath Multiple-AS:

Option B: If every device in the fabric has a different AS number, then enabling Equal-Cost Multi-Path (ECMP) routing requires the multipath multiple-as statement. This configuration allows BGP to consider multiple paths across different AS numbers as equal cost, enabling efficient load balancing across the network.

Same AS Number Configuration:

Option A: It's possible for all leaf devices to use the same AS number in an IP fabric, which simplifies the configuration. EBGP (External BGP) will still function correctly in this setup because BGP considers the peering relationship rather than strictly enforcing different AS numbers in this specific use case.

Conclusion:

Option B: Correct---This statement is essential for enabling ECMP in a multi-AS environment.

Option A: Correct---Leaf devices can share the same AS number without needing special EBGP configuration.

I chose BD. The multipath multiple-as statement is required to enable ECMP if every device has a different AS number. EBGP is only required to route most routing information to external devices outside the fabric.
