Single RS/6000 SP and Single SP Switch Router 183
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:
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@sp2n09:/ netstat -rn
