Configuration  for the PPP over Ethernet Client using PAP protocol 

Example: Configuring a PPPoE Client

 Device> enable 

Device# configure terminal

Device(config)# interface GigabitEthernet 0/0/0

Device(config-if)# no ip address

Device(config-if)# pppoe enable

Device(config-if)# pppoe-client dial-pool-number 1 

Device(config-if)# exit

Device(config)# interface dialer 1

Device(config-if)# mtu 1492 

Device(config-if)# ip address negotiated

Device(config-if)# encapsulation ppp

Device(config-if)# dialer pool 1

Device(config-if)# ppp pap sent-username username1 password pwd1

Device(config-if)# end

Example: Configuring PPPoE on the Server

PPPOE stand for point-to-point -over-ethernet. a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It is used mainly with DSL services where individual users connect to a DSL modem over Ethernet. Ethernet networks are packet-based and have no capacity for a connection or circuit. They also lack basic security features to protect against IP and MAC conflicts and rogue DHCP servers
