ISCW PPPoE Lab sim

Scenario:-
CiscoSims is a small export company .This firm has an existing enterprise network that is made up exclusively of routers that are using EIGRP as the IGP. Its network is up and operating normally. As part of its network expansion, CiscoSims has decided to connect to the internet by a broadband cable ISP. Your task is to enable this connection by use of the information below.



Connection Encapsulation: PPP
Connection Type: PPPoE client
Connection Authentication: None
Connection MTU: 1492 bytes
Address: Dynamically assigned by the ISP
Outbound Interface: E0/0

You will know that the connection has been successfully enabled when you can ping the simulated Internet address of 172.16.1.1

Note: Routing to the ISP: Manually configured default route


Configuration Solution:

Step 1. Configure the Ethernet interface e0/0 (outbound interface) of the router R with a PPPoE client configuration :-

R(config)#int e0/0
R(config-if)#pppoe enable

R(config-if)#pppoe-client dial-pool-number 1
R(config-if)#no shut
R(config-if)#exit

Step 2. Create and configure the dialer interface of the router R for PPPoE with a maximum transmission unit (MTU) size of 1492 and a negotiated IP address (dynamically assigned) :-

R(config)#int dialer 1
R(config-if)#encapsulation PPP

R(config-if)#ip mtu 1492

R(config-if)#dialer pool 1
R(config-if)#ip address negotiated
R(config-if)#exit

Step 3. Configure a static default route on the router R :-

R(config)#ip route 0.0.0.0 0.0.0.0 dialer 1
R(config)#exit

Step 4. Save your configuration:-

R#copy run start

Test your configuration by pinging the provided Internet address :-

R#ping 172.16.1.1
