2.SG-1 as xDSL aggregator using Gigabit Ethernet network
In this scenario, a PPP session is initiated on an Ethernet-connected client through a standard ADSL modem.
The session is transported over the Ethernet and terminated by the SG-1, which is acting as an xDSL
aggregator.
Scenario highlights:
• The SG-1 terminates the PPPoE sessions initiated at users PCs and grants a service.
• User packets are passed as follows:
– The user PC, which runs PPP client, encapsulates the PPP packet with Ethernet.
– The PPPoE packet is being sent from the user PC to the xDSL modem.
– The xDSL modem encapsulates it with DSL.
– The DSLAM de-encapsulates the DSL header and send the Ethernet packets including broadcasts.
– The SG-1 de-encapsulates the Ethernet and terminate the PPP session.
Using the pppoe enable command
The pppoe enable interface command enables PPPoE negotiation for a specific interface in the system.
Usage
