+= Connecting routers
+
+To connect a router to another router in the router network, you configure a 
`connector` on one router to create the outbound connection, and a `listener` 
on the other router to accept the connection.
+
+Because connections are bidirectional, there should only be one connection 
between any pair of routers. Once the connection is established, message 
traffic flows in both directions.
+
+This procedure describes how to connect a router to another router in the 
router network.
+
+.Procedure
+
+. Determine the direction of the connection.
++
+--
+Decide which router should be the "connector", and which should be the 
"listener". The direction of the connection establishment is sometimes 
arbitrary, but consider the following factors:
+
+IP network boundaries and firewalls::
+Generally, inter-router connections should always be established from more 
private to more public. For example, to connect a router in a private IP 
network to another router in a public location (such as a public cloud 
provider), the router in the private network must be the "connector" and the 
router in the public location must be the "listener". This is because the 
public location cannot reach the private location by TCP/IP without the use of 
VPNs or other firewall features designed to allow public-to-private access.
+
+Network topology::
+The topology of the router network may affect the direction in which 
connections should be established between the routers. For example, a 
star-topology that has a series of routers connected to one or two central 
"hub" routers should have "listeners" on the hub and "connectors" on the 
spokes. That way, new spoke routers may be added without changing the 
configuration of the hub.
+--
+
+. On the router that should create the connection, open the 
`{RouterConfigFile}` configuration file and add a `connector`.
 
 Review comment:
   ```suggestion
   . On the router chosen to create the connection, open the 
`{RouterConfigFile}` configuration file and add a `connector`.
