In this scenario, which action will accomplish this task?

You want to enable an EBGP-based IP fabric to allow ECMP routes to be populated into the RIB.

In this scenario, which action will accomplish this task?
A . Enable the forwarding-options ecmp-do-local-lookup parameter.
B . Enable the multipath multiple-as BGP parameter.
C . Enable the routing-options multipath global parameter.
D . Enable the chassis ecmp-alb parameter.

Answer: B

Explanation:

To enable ECMP (Equal-Cost Multi-Path) routes in the Routing Information Base (RIB) in an EBGP-based IP fabric, you should enable the ‘multipath multiple-as’ BGP parameter. This setting allows the use of multiple paths for BGP routes even when they come from different autonomous systems, which is key in a typical EBGP deployment in a data center IP fabric.
