Chapter 1 Overview of the system

1.1 Introduction

The LDK24 including ADSL option card have an ADSL router functionality used for Internet/LAN access via an ADSL line. LDK24 ADSL Router can run maximum upstream transmission rates of 640Kbps and maximum downstream transmission rates of 8Mbps. The actual rate depends on the copper category of your telephone wire, distance from the central office and the type of ADSL service subscribed to. See the sections below for more background information on DSL and ADSL.

1.1.1 What is ADSL ?

It is an asymmetrical technology, meaning that the downstream data rate is much higher than the upstr eam data rate. As mentioned, this works well for a typical Internet session in which more information is downloaded, e.g., from Web servers, than is uploaded. ADSL operates in a frequency range that is above the frequency range of voice services, so the tw o systems can operate over the same cable. What are the advantages of ADSL from the point of view of the Network Service Provider (NSP) and the end user?

Chapter 2 Configuring LDK24 System via Console

This chapter describes how to configure LDK24 ADSL Router System in typical Gateway configurations by Console.

2.1 Introduction

This chapter describes how to configure the LDK24 ADSL Router Syste m in various gateway configurations:

• Bridged configurations:

• Ethernet - RFC1483/RFC2684 bridged

• Routed configurations:

• Ethernet - IPoA routed

• Ethernet - RFC1483/RFC2684 routed

• Ethernet - PPP routed.

• Ethernet - PPPoE Client over RFC1483/RFC2684.

2.2 Bridged configurations

All of the configurations in this section use ISOS Bridge module to bridge between Ethernet and an ATM protocol. These configurations are bridging at Layer 2.

2.2.1 Ethernet - RFC1483/RFC2684 bridged

1. Clear any existing Brid ge interfaces and Ethernet and RFC1483/RFC2684 transports, by

entering the following commands:

- - > bridge clear interfaces

- - > transports clear

2. Add an Ethernet device to the Bridge. In the following commands

--> ethernet add transport <name> [<port>]

--> bridge add interface <name>

--> bridge attach {<name>|<number>} <transport>

Example)

- -> ethernet add transport eth1 ethernet

- -> bridge add interface bridge1 bridge attach bridge1 eth1

3. Add an RFC1483 device to the Bridge, with RFC1483 configured to run on port, using VCI and LLC encapsulation.

- -> rfc1483 add transport <name> <port> <vpi> <vci> {llc|vcmux} {bridged|routed}

LDK24 ADSL Router User’ s Manual

Version 1.0D

Page 9 of 67

- -> bridge add interface <name>

- -> bridge attach {<name>|<number>} <transport>

Example)

- -> rfc1483 add transport my1 483 a1 0 600 llc bridged

- - > bridge add interface bridge2

- - > bridge attach bridge2 my1483

2.3 Routed configurations

All of the configurations in this section use the ISOS ip module to route between Ethernet and an ATM protocol. As these configurations perform IP routing, each part of the network must be on a different subnet.

2.3.1 Ethernet - IPoA routed

1. Clear any existing IP interfaces and transports. Clearing the IP interfaces also deletes any

existing DHCP client settings on those interfaces. This change to DHCP is not updated in the DHCP client configuration until you enter the dhcpclient update command.

- -> ip clear interfaces

- -> ip clear routes

- -> transports clear

- -> dhcpclient update

2. Add the Ethernet device to the router.

- -> ethernet add transport <name> [<port>]

- -> ip add interface <name> [<ipaddress> [<netmask>]]

- -> ip attach {<name>|<number>} <transport>

Example)

- -> ethernet add transport eth1 ethernet

- - > ip add interface ip1 192.168.101.2

- - > ip attach ip1 eth1

3. Add the IPoA device to the router configured to run on VCI with a peak cell rate, using the

port.

- -> ipoa add transport <name> pvc <atm-port> <vpi> <vci>

- -> ip add interface <name> [<ipaddress> [<netmask>]]

- -> ip attach {<name>|<number>} <transport>

- -> ipoa transport {<name>|<number>} set pvc <pvc number> pcr <peak cell rate>

Example)

LDK24 ADSL Router User’ s Manual

Version 1.0D

Page 10 of 67

- -> ipoa add transport ipoa1 pvc a1 0 700

- -> ip add interface ip2 192.168.102.2

- -> ip attach ip2 ipoa1

- -> ipoa transport ipoa1 set pvc 1 pcr 50000

4. Add a default route .

- -> ip add route <name> <dest_ip> <netmask> {[gateway <gateway_ip>]|[interface interface>]}

example)

- -> ip add route default 0.0.0.0 0.0.0.0 gateway 192.168.102.3

2.3.2 Ethernet –RFC1483/RFC2684 routed

1. Clear any existing IP interfaces and transports. Clearing the IP interfaces also deletes any

existing DHCP client settings on those interfaces. This change to DHCP is not updated in the DHCP client configuration until you enter the dhcpclient update command.

- -> ip clear interfaces

- -> ip clear routes

- -> transports clear

- -> dhcpclient update

2. Add the Ethernet device to the router.

- -> ethernet add transport <name> [<port>]

- -> ip add interface <name> [<ipaddress> [<netmask>]]

- -> ip attach {<name>|<number>} <transport>

Example)

- -> ethernet add transport eth1 ethernet

- - > ip add interface ip1 192.168.101.2

- - > ip attach ip1 eth1

3. Add the RFC1483 device to the router, with RFC1483 configured to run on port using VCI,

vcmux routed or llc encapsulation.

- -> rfc1483 add transport <name> <port> <vpi> <vci> {llc|vcmux} bridged|routed}

- -> ip add interface <name> [<ipaddress> [<netmask>]]

- -> ip attach {<name>|<number>} <transport>

example)

- -> rfc1483 add transport my1483 a1 0 600 vcmux routed

- -> ip add interface ip2 192.168.102.2

LDK24 ADSL Router User’ s Manual

Version 1.0D

Page 11 of 67

- -> ip attach ip2 my1483

4. Add a default route .

- -> ip add route <name> <dest_ip> <netmask> {[gateway <gateway_ip>]|[interface interface>]}

example)

- -> ip add route default 0.0.0.0 0.0.0.0 gateway 192.168.102.3

2.3.3 Ethernet - PPP routed

1. Clear any existing IP interfaces and transports. Clearing the IP interfaces also deletes any

existing DHCP client settings on those interfaces. This change to DHCP is not updated in the DHCP client configuration until you enter the dhcpclient update command.

- -> ip clear interfaces

- -> ip clear routes

- -> transports clear

- -> dhcpclient update

2. Add the Ethernet device to the router.

- -> ethernet add transport <name> [<port>]

- -> ip add interface <name> [<ipaddress> [<netmask>]]

- -> ip attach {<name>|<number>} <transport>

Example)

- -> ethernet add transport eth1 ethernet

- - > ip add interface ip1 192.168.101.2

- - > ip attach ip1 eth1

3. Add the PPP device to the router. The PPP module supports multiple simultaneous

connections.

- -> pppoa add transport <name> dialout pvc <interface> <port> <vpi>

<vci>

- -> ip add interface <name> [<ipaddress> [<netmask>]]

- -> ip attach {<name>|<number>} <transport>

Example)

- -> pppoa add transport ppp1 dialout pvc 1 a1 0 800

- -> ip add interface ip2

- -> ip attach ip2 ppp1

CHAP or PAP authentication can be used; PPP needs a username and password.

--> pppoa set transport {<name>|<number>} welogin {none|auto|pap|chap}

--> pppoa set transport {<name>|<number>} username <username>

LDK24 ADSL Router User’ s Manual

Version 1.0D

Page 12 of 67

--> pppoa set transport {<name>|<number>} password <password>

example)

- -> pppoa add transport ppp1 dialout pvc 1 a1 0 800

- -> ip add interface ip2

- -> ip attach ip2 ppp1

- -> pppoa set transport ppp1 welogin chap

- -> pppoa set transport ppp1 username fred

- -> pppoa set transport ppp1 password password

2.3.4 Ethernet - PPPoE

1. Clear any existing IP interfaces and transports, and update the DHCP client configuration.

- -> ip clear interfaces

- -> transports clear

2. Add the Ethernet device to the router.

- -> ethernet add transport <name> [<port>]

- -> ip add interface <name> [<ipaddress> [<netmask>]]

- -> ip attach {<name>|<number>} <transport>

Example)

- -> ethernet add transport eth1 ethernet

- - > ip add interface ip1 192.168.101.2 255.255.255.0

- - > ip attach ip1 eth1

3. The PPPoE BUN driver uses functionality provided by the PPP module. Configure a PPP

channel for an outgoing PPPoE connection to the remote AC using PVC. The PPPoE AC utilizes CHAP authentication or PAP authentication. If no authentication is used, simply omit the welogin command. Since the PPP module supports multiple, simultaneous connections, we can be using PPP device 1 and Interface 1. PPP is able to automatically configure the IP address of the router interface, and add a default route when the connection is made. This is the reason the IP address of the router interface is not specified in the command:

- -> ip add interface <name> [<ipaddress> [<netmask>]]

- -> pppoe add transport <name> dialout pvc <interface> <port> <vpi> <vci> [accessconcentrator <concentrator>] [servicename <servicename>]

- -> ip attach {<name>|<number>} <transport>

- -> pppoe set transport {<name>|<number>} welogin {none|auto|pap|chap}

- -> pppoe set transport {<name>|<number>} username <username>
