Additional Configuration of Router Modes
In a typical routed configuration, the ADSL router is treated as a separate device on the
network that the PC and DSLAM send packets to. The Ethernet and ADSL networks are
configured as separate IP subnets. The PC must have the ADSL router set up as its
default gateway. Descriptions of the protocols supported in this mode of operation are
discussed in the next sections.
Dynamic IP for WAN IP
Following settings are necessary when working under this mode:
• VPI/VCI
• Encapsulation: 1483 Bridged IP LLC
• Bridged: Disabled
• NAT Configuration: NAPT
Please see scenario 2: Router Mode Configuration with Dynamic IP in Appendix for
more detail configuration.
Static IP for WAN IP
Following settings are necessary when working under this mode:
• VPI/VCI
• Static IP Address: provided by ISP
• Subnet Mask: provided by ISP
• Default Gateway: provided by ISP
• Encapsulation: 1483 Bridged IP LLC or 1483 Routed IP LLC (provided by ISP)
• Bridged: Disabled
• NAT Configuration: NAPT
• Preferred DNS server: IP is Provided by ISP
Please see scenario 3: Router Mode Configuration with Static IP in Appendix for more
detail configuration.
PPPoA ( RFC 2364)
PPP is a widely used protocol for controlling a point-to-point link. It is used by existing
ISPs (Internet Service Providers) in providing dial-in services for the Internet. It can be
used over a variety of physical media to transport IP data, MAC data, and many other
data types. Components of PPP have been defined which provide option negotiation,
compression, encryption, authentication and multi-link facilities. For Xdsl deployment,
authentication is probably the single most important of these.
Following settings are necessary when working under this mode:
• VPI/VCI
• Encapsulation: PPPoA VC-Mux
• Bridged: Disabled
• PPP User Name: Provided by ISP
