3Com 10014299 manual Configure a PPPoE session, Configure the LAN interface and the default route

Typical PPPoE Configuration Example 183

[Router-Dialer1]ipppp-negotiate

[Router-Dialer1]ppp pap local-user 3com password cipher 12345

2Configure a PPPoE session

[Router]interface ethernet 1 [Router-Ethernet1]pppoe-client dial-bundle-number 1

3Configure the LAN interface and the default route

[Router]interface ethernet 0

[Router-Ethernet0]ip address 192.168.1.1 255.255.255.0

[Router]ip route-static 0.0.0.0 0.0.0.0 dialer 1

Use ADSL as Standby Line

If the IP addresses assigned to the PCs on the LAN are private addresses, Network Address Translation (NAT) should also be configured on the router. For the NAT configuration, refer to the related chapters contained in Operation Manual - Network Protocol.

I. Networking Requirements

RouterA uses both DDN leased line and ADSL to connect with the network center and ADSL is used as a standby for the DDN leased line. Thus, if the DDN leased line fails, RouterA can still originate PPPoE call for connection to the network center across ADSL. If ADSL has been idle for two minutes, the PPPoE session will be terminated. If new packets are generated for transmission after that, PPPoE session will be re-established.
