The customer is implementing a full-mesh fabric with four 9506 MDS Connectrix Directors. Each
director in the mesh will be connected with dual connection port channels to a neighboring switch,
giving the fabric a cost of 250 between each director. The hosts in the environment must pass
through two directors to access storage, with an aggregate link cost from the host to the storage of
500. What happens in this environment if a link fails in a port-channel group?

A.
FSPF is not recalculated, it keeps the same cost

B.
The SRC-DEST-EXCH routing will allow for a link down event and for fabric reconfiguration to
propagate to the nearest peer in the fabric

C.
The cost changes to 500 between switches, the packets take alternate paths while the link
either comes online or is marked failed

D.
The OX-DEST-EXCH routing will not allow for a link down event and the fabric will become
segmented
