RE: PPPOE issue

You said previously that it was working back-to-back. It should work with the switch in the middle.

But looking to your configs, it seems you are mixing the old and the new way to configure PPPoE.

Look bellow the options you have and correct your configs accordingly.

1) PPPoE Server (new format-after 12.2(15)T)
!
bba-group pppoe global
 virtual-template 1
!
interface Virtual-Template1
 ip address 150.1.45.5 255.255.255.0
!
interface Ethernet1/1
 pppoe enable group global
!

2) PPPoE Client (new format-after 12.2(13)T)
!
interface Dialer1
 mtu 1492
 ip address 150.1.45.4 255.255.255.0
 encapsulation ppp
 dialer pool 1
 dialer persistent
!
interface Ethernet1/1
 pppoe enable
 pppoe-client dial-pool-number 1
!

3) PPPoE Server (old format-before 12.2(15)T)

R3:
interface Ethernet0/1
pppoe enable
!
interface Virtual-Template1
ip address 142.1.35.3 255.255.255.0
!
vpdn enable
!
vpdn-group PPPoE
accept-dialin
protocol pppoe
virtual-template 1
!

4) PPPoE Client (old format-before 12.2(13)T)

R5:
interface Ethernet0/0
pppoe enable
pppoe-client dial-pool-number 1
!
interface Dialer1
mtu 1492
ip address 142.1.35.3 255.255.255.0
encapsulation ppp
dialer pool 1
!
vpdn enable
!
vpdn-group PPPoE
 request-dialin
  protocol pppoe
!

But if i change the config to this:

R1:

vpdn enable

vpdn-group 1
request-dialin
protocol pppoe

interface fa0/1
ip address dhcp
pppoe enable group global
pppoe-client dial-pool-number 1

interface Dialer1
ip unnumered fa0/1
encapsulation ppp
dialer pool 1
ppp chap hostname cisco
ppp chap password cisco

R6:
username cisco password cisco

vpdn enable

vpdn-group 1
accept-dialin
protocol pppoe
virtual-template 1

ip dhcp excluded-address 172.10.16.2 172.10.16.254
ip dhcp pool PPPOE
network 172.10.16.0 255.255.255.0

interface fa0/1
ip address 172.10.16.6 255.255.255.0
pppoe enable group global

interface virtual-template 1
ip unnumbered fa0/1
no peer neighbor-route

I get allocated an ip address from DHCP server (R6) but my vpdn tunnel does
not come up.

Very strange
