+Used to add a Lustre node to a specified Lustre cluster through a network
+ interface.
+ In this example, Lustre node adev3 has been added to 2 Lustre clusters
+ whose cluster_id are 0x1000 and 0x2000 separately through 2 network interface
+ cards: adev3-eth0 and adev3-eth1.
+ adev3 would listen in some specified port(s) to prepare for possible connection
+ requests from nodes in these two clusters.

-Real life examples are given in the Lustre-conf manual page.
+Used to add a route entry for a Lustre node.
+ Here Lustre node adev3 is told it has a new route entry that now it could
+ send packets to Lustre nodes whose nids is from 4 to 7 with the help of
+ Lustre gateway node whose nid is 5.
+ Besides, Lustre gateway node is in cluster whose id is 0x1000 and target
+ of the route belongs to cluster whose id is also 0x1000.
+ The network in this route path is a tcp network.
