ADSL Router configuration

Router Installation and Configuration Manual/Configuring an ADSL

ADSL over PPPOE Configuration
the config of the ATM ADSL interface for PPPoE over ATM can be:
interface ATM0/0
no ip address
no ip mroute-cache
no atm ilmi-keepalive
dsl operating-mode auto
pvc 8/35
  encapsulation aal5mux ppp dialer
  dialer pool-member 2
interface Dialer2
description PPPoverATM
ip address negotiated
encapsulation ppp
dialer pool 2
dialer-group 2
use the right VPI/VCI as per provider specs
the pool-number must point to the number in the dialer config.
Define the dialer list
To be able to have PPPoE client over ATM interface all on the router:
follow the next link:
the key point is: 
interface ATM0.1 point-to-point
pvc 8/35
  enc aal5mux
  pppoe-client dial-pool-number 1

there are many variations as you can see (Excerpts)
ADSL Setup
PVC ConnectionThe Gateway supports up to eight Private Virtual Circuit (PVC) connections. Default PVC addresses are as follows: 0/35, 8/35, 0/43, 0/51, 0/59, 8/43, 8/51, and 8/59.

Select Connection
Select the connection you want to configure.

Enable Now
Select this option to enable the selected connection. By default, only PVC 1 is enabled. The other seven PVCs are disabled. You must enable them before configuring layer 3 connections on top of them. To configure the PVC settings separately from the Wide Area Network (WAN) connections, you can save the PVC settings separately. Click Save PVC.

NOTE: PVCs are layer 2 (physical and link), while WAN connections are layer 3, meaning IP and Point-to-Point (PPP) connections. For each PVC, you can configure up to one IP connection and up to four PPPoE (PPP over Ethernet) connections.

Connection TypeConfigure the appropriate encapsulation method of the WAN connection. Each Basic Setup screen and available features will differ depending on which encapsulation method you select. These are the available methods:
IPoE (RFC2684 Bridged)
IPoA (RFC2684 Routed)
PPPoE (RFC 2516)
PPPoA (RFC 2364)

Common Settings Primary DNS
Primary DNS server IP on this connection, used to manually override DNS settings from DHCP client.

Secondary DNS
Secondary DNS server IP on this connection, used to manually override DNS settings from DHCP client.

To use Network Address Translation, keep the default Enabled. Otherwise, select Disabled.

IGMP Forwarding
Allow user to control IGMP Forwarding on this connection, to allow IGMP Forwarding select Enabled. Otherwise, select Disabled.

Dedicate The Connection To Voice (FXS1/FXS2)
Choose if to use this connection for FXS1/FXS2 outbound phone calls. Note that among all Internet connections at most one can set this to Enabled.

The 802.1Q VLAN ID to be used on egress to the interface associated with this connection. A value of -1 indicates that no VLAN tagging for this connection.

802.1p Mark
802.1p (ethernet priority) to mark traffic sent out on this connection. A value of -1 indicates no change from the incoming packet.

Override Ethernet Priority
If false, if 802.1p Mark is specified, is applied only to packets of priority 0. If true, the 802.1p Mark, if specified, is to be applied to all packets on this connection.

RIP Recv Packet Version
Select the Routing Information Protocol (RIP) version you want to use: RIP off, RIPv1, or RIPv2.

Domain Name
Enter the Domain Name manually assigned for this connection, DNS proxy will compare domain name to decide which connection to send out DNS queries if this value is not empty.

NOTE: You can configure the hierarchical shaping rate on the PVC link level or layer 3 connection level. Usually shaping is configured on the PVC link level, matching the service provider's upstream speed, to help enforce QoS rules and avoid packet dropping in the service provider's head-end device (for example, DSLAM).
