Your FC-to-FC backbone fabric has two operational links to the same edge fabric. The first
link is an EX_Port and the second link is a VEX_Port. Your implementation requires that
both paths are used to actively carry traffic.Which statement describes how to enable both
links to simultaneously carry traffic?
A.
The link on the VEX_Port requires the Advanced Extension license.
B.
The link cost on the VEX_Port needs to be lower than the EX_Port link cost.
C.
The link cost on the VEX_Port needs to be equal to the EX_Port link cost.
D.
The link cost on the VEX_Port needs to be higher than the EX_Port link cost.
“EX_Ports and VEX_Ports, when connected, are assigned different router port costs and traffic will flow only through the EX_Ports. Routing failover is automatic, but it can result in frames arriving out of order when frames take different routes.”
We can change the cost of VEX_Port to be equal the EX_Port link so that they can carry traffic through two port.
