The correct answer is B. The multipath multiple-as statement is required to enable ECMP if every device has a different AS C. Only a single point to point EBGP session is required between peers in an IP fabric.. When each device in the IP fabric has a different AS number, the BGP "multipath multiple-as" statement must be enabled to allow ECMP (Equal-Cost Multi-Path) across EBGP peers with EBGP sessions in an IP fabric are established as single point-to-point sessions between directly con

Question

Which two statements are correct about an IP fabric? (Choose two.)

Options

AAll leaf devices can use the same AS number in an IP fabric without making any adjustments to
BThe multipath multiple-as statement is required to enable ECMP if every device has a different AS
COnly a single point to point EBGP session is required between peers in an IP fabric.
DEBGP is only required to route most routing information to external devices outside the fabric.

Explanation

When each device in the IP fabric has a different AS number, the BGP "multipath multiple-as" statement must be enabled to allow ECMP (Equal-Cost Multi-Path) across EBGP peers with EBGP sessions in an IP fabric are established as single point-to-point sessions between directly connected devices, typically leaf-to-spine, allowing for scalable and straightforward peering.
