•If ARP is disabled on the SP Switch network, the IP addresses assigned to the nodes must be determined by the switch node numbers.
Note: The SP Switch Router Adapter card will not properly forward IP data to nodes assigned with an IP address that is in another subnet.
Configuration:
In this scenario, we have the SP Switch of SP21 connected to the GRF 1600. The GRF 1600 has its ATM
