Configuration:
For this scenario, the following routes have to be set:
1.On node 11, node 12 and node 15 in SP2, add the following route to the switch network of partition 1 of SP2:
route add
192.168.13.129
The MTU size of 65520 is the optimum size for the SP Switch network.
2. Check for correct routing entries, for example:
root@sp2n11:/ netstat |
