Learning PPPOE configuration (1)

In terms of configuration, PPPoE always has many advantages. The following describes the configuration of PPPOE server and Cisco PPPOE. First, create a broadband connection named libin password libin on your computer and configure it on ATM1.

Configure on R1 first, pppoe Client

 
 

  
  
R1 (config) # vpdn enable VPDN
  
  
R1 (config) # vpdn-group CISCO defines the group name CISCO
  
  
R1 (config-vpdn) # request-dialin request access
  
  
R1 (config-vpdn-req-in) # PROtocol pppoe
  
  
% PPPoE config from vpdn-group is converted to pppoe-profile based config.
  
  
% Continue PPPoE configuration under 'bba-group pppoe global'
  
  
R1 (config-vpdn-req-in) # exit
  
  
R1 (config-vpdn) # exit
  
  
R1 (config-if) # no ip address
  
  
R1 (config-if) # pppoe enable
  
  
R1 (config-if) # pppoe-client dia
  
  
R1 (config-if) # pppoe-client dial-pool-number 1
  
  
R1 (config-if) # ^ Z
  
  
R1 # conf t
  
  
R1 (config-if) # ip add?
  
  
A. B .C.D IP address
  
  
Dhcp IP Address negotiated via DHCP
  
  
Negotiated IP Address negotiated over PPP
  
  
Pool IP Address autoconfigured from a local DHCP pool
  
  
R1 (config-if) # ip add negotiated
  
  
R1 (config-if) # ip nat outside
  
  
R1 (config-if) # encapsulation ppp
  
  
R1 (config-if) # dialer pool 1
  
  
R1 (config-if) # ppp chap hostname
  
  
R1 (config-if) # ppp chap hostname cisco
  
  
R1 (config-if) # ppp chap password 0 cisco
  
  
R1 (config-if) # ip route 0.0.0.0 0.0.0.0 dialer0
 
 

Configure aggregation routing on R2

R2(config-if)#exit

Configure ATM1

 
 

  
  
ATM1#conf t  
  
  
ATM1(config)#no ip routing  
  
  
ATM1(config)#int fast0/0

Configure BBA-Group

 
 

  
  
ATM1 (config) # bba-group pppoe global
  
  
ATM1 (config-bba-group) # virtual-template 1 virtual touch version is defined as 1
  
  
ATM1 (config-bba-group) # exit
 
 

Configure Virtual-Template

 
 

  
  
ATM1 (config) # interface virtual-template 1
  
  
ATM1 (config-if) # ip unnumbered loopback 0 borrow the ip address on loopback 0
  
  
ATM1 (config-if) # encapsulation ppp encapsulation to ppp
  
  
ATM1 (config-if) # ppp authentication chap authentication is chap
  
  
ATM1 (config-if) # peer de
  
  
ATM1 (config-if) # peer default ip add pool cisco allocates ip addresses from cisco
