Configuration 5B:R8csi  R8r (2 C-LANs)  R8si 
In this configuration, a DEFINITY ECS R8r acts as a gateway between two other 
nodes — one connected via ppp to an R8csi and the other via ethernet to another R8si. 
This configuration is the same as configuration 5A except that Switch 1 has two 
C-LAN circuit packs instead of one. One C-LAN handles the ppp connection and the 
other handles the ethernet connection.  
Task Summary
The following tasks need to be completed for Switch 1, Switch 2, and Switch 3:

Subnet Mask Enter the subnet mask associated with the IP address for 
this IP interface. (The IP address is associated with the 
node name on the Node Names screen). 
In this example, leave the default subnet mask, 
255.255.255.0, which indicates no subnetting for a Class 
C IP address.
See the discussion of subnetting , Subnetting  (page 16), 
in Chapter 1 and Configuration 1: R8r  R8si  
(page 60) in this chapter for details about subnet masks.
Gateway Addr Leave blank for this configuration. The only connection 
to this IP interface is node-3 on Switch 3, which is on the 
same subnetwork as this IP interface, so no gateway is 
needed.
In general, for connectivity to other (sub)networks, enter 
the address of a network node that will serve as the 
default gateway to the other (sub)networks.
Net Rgn Enter the region number for this IP interface. Field Conditions/Comments
