Router
NSP1
155.1.2.2 155.1.2.1
155.1.3.1
*If DSL card is an 8540 DSL card,
associated RTU will not have an IP address.
DSL Routing Table
Host/Net Subnet Mask
1) 155.1.3.4
255.255.255.255
2) 155.1.3.4
255.255.255.255
3) 155.1.3.6
255.255.255.255
4) 155.1.3.6
255.255.255.255
The RTU forwards upstream any traffic on its LAN interface for which it does not
know the host.
