 +The two routers allocate IP addresses using DHCP. In order to facilitate the usage of the platform, fixed allocations are configured for the end hosts. This is configured in ''/etc/config/dhcp'' on each router as in the following.  
 +
 +<file /etc/config/dhcp>
 +config dhcp 'lan'
 +        option interface 'lan'
 +        option start '100'
 +        option limit '150'
 +        option leasetime '12h'
 +        option dhcpv6 'server'
 +        option ra 'server'
 +
 +config host
 +        option name 'pi2'
 +        option mac 'b8:27:eb:0f:f8:95'
 +        option ip '192.168.200.192'
 +
 +config host
 +        option name 'pi3'
 +        option mac 'b8:27:eb:20:aa:54'
 +        option ip '192.168.200.193'
 +</file>
 +
 +Finally, we verify the routing and addressing on the Raspberry Pi devices using ''ifconfig'' (or ''ip addr show'') and ''ip route'' commands. 
 +
