If a 4-port LAG is configured with the option of 'port-threshold 2' and 'action down' what will happen if the total operational links in the LAG is 2?

  1. If dynamic-cost is enabled it will adjust the cost for routing protocols such as OSPF.
  2. If dynamic-cost is not enabled it will adjust the cost for routing protocols such as OSPF by dividing the link bandwidth by 2.
  3. The LAG will be changed to an operational state of 'down'.
  4. The LAG will function with only 2 ports. There will be no change to the routing metric.
