Hi,
I am using Cisco 7200 router as the BRAS which allow pppoe termination. How do I make sure the username: xxxx can only be used to login one time at a time! Meaning, to say, once somebody already login to my system using this username, then, the second person trying to use the same username will be rejected by BRAS. My configuration is as below:
!
username xxxx user-maxlinks 1 password xxxx
!
vpdn enable
!
vpdn-group 1
accept-dialin
protocol pppoe
virtual-template 1
pppoe limit per-mac 1
!
interface FastEthernet0/0.1
encapsulation dot1Q 3
ip address 203.x.x.x.255.255.128
pppoe enable
!
interface Virtual-Template1
mtu 1492
ip unnumbered FastEthernet0/0.1
peer default ip address pool mango1
ppp authentication pap callin
!
ip local pool mango1 203.x.x.x.115.25.119
!
