Re: PPPoE configuration on Cisco 1941

netopia · ‎03-20-2012

I have recently gotten a cisco 1941 router running version 15.1(3)T, and am trying to configure the router as a PPPoE server for access via a vlan on one of the gigabit ethernet ports.

I currently have a cisco 2620 router (version 11.3(2)XA4) with the following relevant configurations:

vpdn enable

vpdn multihop

vpdn domain-delimiter @ suffix

!

vpdn-group pppoe

accept-dialin

protocol pppoe

virtual-template 1

!

interface Loopback1

description loopback for PPPoE

ip address 163.176.94.193 255.255.255.192

!

interface FastEthernet0/0.301

description PPPoE interface

encapsulation dot1Q 301

no ip route-cache

no ip mroute-cache

pppoe enable

!

interface Virtual-Template1

description PPPoE interface

mtu 1492

ip unnumbered Loopback1

ip mroute-cache

peer default ip address pool PPPnet

ppp authentication chap pap

ppp ipcp dns 163.176.4.23

!

I am trying to duplicate this (all but IP addresses) on the new router, but there are some options that do not seem to exist in this particular software/hardware combination. Specifically,

vpdn-group pppoe

accept-dialin

protocol pppoe

does not accept "pppoe" as a protocol, only allowing l2tp. I am hoping that someone can tell me what has changed, and what the proper configuration is.

Thanks,

@ Ben

bba (broadband association) group config is used instead of vpdn

================================

R1(config)#bba-group pppoe global

================================

so your config will be as follows:

!

bba-group pppoe global

virtual-template 1

!

interface Loopback1

description loopback for PPPoE

ip address 163.176.94.193 255.255.255.192

!

interface FastEthernet0/0.301

description PPPoE interface

encapsulation dot1Q 301

no ip route-cache

no ip mroute-cache

pppoe enable group global

!

interface Virtual-Template1

description PPPoE interface

mtu 1492

ip unnumbered Loopback1

peer default ip address pool PPPnet

ppp authentication chap pap

ppp ipcp dns 163.176.4.23

!

===================================

R1(config)#interface FastEthernet0/0.301

R1(config-subif)#pppoe enable group global

===================================

I have highligted the changes in between ===. everything else remains same. Plz let me know if this helped. Thanks.
