+''' Mininet Cluster Edition '''
+
+Mininet supports running a network across a set of nodes (cluster). Currently, this relies on SSH tunnels, and is experimental. To enable cluster support, on each node that will be part of the cluster:
+
+ 1. Generate and exchange SSH keys. If we are running a tiny cluster of node1-1 and node1-2: 
+ {{{
+ssh-keygen -t rsa
+ssh-copy-id root@node1-1
+ssh-copy-id root@node1-2
+ }}}
+ Note how a node also has to have its own key in authorized_keys, so we run `ssh-copy-id` against every node in the cluster.
+
+ 2. Edit ''/etc/ssh/sshd_config'', adding the following two lines:
+ {{{
+AllowTCPForwarding yes                                                                                
+PermitTunnel yes
+ }}} 
+
+ 3. restart `sshd`
+ {{{
+service ssh restart
+ }}}
+
+If all goes well, you should be able to run the following to run a tree topology across nodes1-1 and node1-2:
+{{{
+# mn --cluster node1-1,node1-2 --topo tree,2,3
+}}}
+
+The virtual switches are distributed randomly across the two nodes, as indicated as part of the above command's output:
+{{{
+*** Placing nodes
+h1:node1-1 h2:node1-1 h3:node1-1 h4:node1-2 h5:node1-2 h6:node1-2 h7:node1-2 h8:node1-2 h9:node1-2 s1:
+node1-1 s2:node1-1 s3:node1-2 s4:node1-2 
+}}}
+
+If you have a controller running remotely, you can append the ''--controller remote,ip=x.x.x.x'' argument like in a regular `mn` command.
