3.Add the route to the Switch network of SP21 on all four nodes of SP2 with an FDDI interface.

On node 9-12 in SP2, add the following route:

route add -net 192.168.14 -netmask 255.255.255.0 -mtu 4352 10.10.1.13

4. Check for correct routing entries on all four nodes, for example:

root@sp2n09:/ netstat -rn

5.On the nodes in SP21 that are supposed to communicate with the four different FDDI backbones (that are logically only one LAN), add the necessary route:

route add -net 10.10.1 -netmask 255.255.255.0 -mtu 4352 192.168.14.4

The -mtu parameter is optional but should be set to ensure optimal packet size on this route.

6. Check for correct routing entries, for example:

root@sp21n01:/ netstat -rn
