ip route add default 0.0.0.0 192.168.102.3 0:0:0:0
The next command configures the IPoA protocol to run on PVC 700 with a
peak cell rate of 50000 cells per second, using the port named “atm”:
ip ipatm pvc add ipoa atm 700 pcr 50000
Save the configuration and reboot the system.

2.9 PPP Routing
When configured for PPP, data is routed between Ethernet and PPP over ATM.
The PPP data runs over a PVC between the modem and the service provider.
The IP address and PVC need to be defined by the service provider. Since the
modem is routing, an IP address needs to be assigned on both modem’s
interfaces. The PC’s default gateway must be set to the Ethernet IP address of
the modem.
The following configuration must be performed to set up the modem:
Add the Ethernet device to the router and assign it an IP address. In the
command, “ethernet” is a label used to refer to this device. The arguments
“ether” and “//edd” are required for an Ethernet device.
ip device add ethernet ether //edd 192.168.101.2
Add the PPP device to the router and assign it an IP address. In the following
command, “ppp_device” is a label for this device. The argument “ether” is
required for a PPP device. The PPP module supports multiple simultaneous
connections, so we explicitly specify Device 1.
ip device add ppp_device ether //ppp/DEVICE=1
We will be using PPP Device 1 and Interface 1, which are able to automatically
configure the IP address of the router interface and add a default route, when the
connection is made. That is why the IP address of the router interface was not
specified in the previous command.
The following command configures PPP Device 1 for dial-out on PVC 700.
CHAP authentication will be used; PPP will supply a username of “fred” and a
password of “password”.
ppp 1 pvc 700 ip
