PPPOE issue

Hi GS.

I am having a problem setting up PPPOE.

here is my setup:

R1 --- SW1(fa0/1) ---- SW1(fa0/6) ---- R6

I have tested this with just using back to back connections and it works but
when i add the switch to the equation I cannot get this to work.

any assistance will be greatly appreciated.

R1:

vpdn enable

vpdn-group 1
request-dialin
protocol pppoe

interface fa0/1
no ip address
pppoe enable group global
pppoe-client dial-pool-number 1

interface Dialer1
ip address dhcp
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
pppoe enable group global

interface virtual-template 1
ip address 172.10.16.6 255.255.255.0
no peer neighbor-route

I also tested with adding the "ip address dhcp" under the physical interface
this works (i get an ip address from the dhcp server) but my vpdn tunnel
does not come up.

what am I doing wrong.
