You have configured your Brocade VCS Fabric to connect to a third-party switch using
multiple links from two RBridges in your fabric. From the fabric, you configure a static vLAG
for these links. You then receive complaints about network performance and notice a
significant CPU load on the third-party switch.
What is the problem?

A.
The RBridge system IDs do not match.

B.
Spanning tree needs to be configured on the vLAG.

C.
The RBridges are not directly adjacent in the fabric.

D.
The third-party switch is incorrectly configured.
