5 • DSL Basic Configuration
Next, you will need to create a WAN profile, create a WAN interface, and create a subscriber. Then, you can
configure the DSL port (port dsl 0 0) for PPPoE.
Follow this example:
profile napt eth_dsl
context ip router
interface eth_dsl
ipaddress unnumbered
point-to-point
use profile napt eth_dsl
tcp adjust-mss rx mtu
tcp adjust-mss tx mtu
subscriber ppp MySubscriber
dial out
authentication chap
identification outbound <username> password <password>
bind interface eth_dsl router
port dsl 0 0
pvc vpi 8 vci 35
pppoe
session MyISP
bind subscriber MySubscriber
no shutdown
The line -
use profile napt eth_dsl -
defines that the NAPT profile <
profile>
will be used on the ip inter-
face
<name>
. For PPPoE, you will only use outbound for identification. You will want to use authentication,
which is why you bind to a subscriber. You can use authentication chap or authentication pap. The line -
bind
subscriber MySubscriber
- binds the PPPoE session to the PPP subscriber, in case authentication is required.
If you do not use authentication, then you will not have a subscriber and you will bind directly to the interface.
Configuration Summary
The modems offer multiple bridged Ethernet connections through logical channels within the DSL link. A
logical connection is called a Permanent Virtual Circuit (PVC) and is identified by a VPI/VCI number pair.
Consult your provider's configuration instructions for connections used on your DSL link. You define those
PVCs inside "port dsl 0 0":
port dsl 0 0
pvc vpi 8 vci 35
Iin the mode "pvc", you define what to do with the bridged Ethernet connection it offers:
•
Bind one or more IP interfaces when your providers uses fixed ip addresses or DHCP in the network
•
Enter PPPoE mode and define a PPP session if the provider is using PPPoE.
Note
PPPoA is not supported.
