Hi
Have a VPLS service (a Layer 2 virtual-cct) from BT in the UK.
It is an FTTC presentation over a PSTN line, not the usual Ethernet presentation.
Looked at various articles and the usual story, no exact fit for our case and facts in one article seem slightly at odds with what it says in another.
http://www.cisco.com/c/en/us/td/docs/routers/access/interfaces/NIM/software/configuration/guide/vdsl2-and-adsl2-nim.html#concept_C76827E4B2B343379FC901F654CD3438
is the best fit, and it says :-
" All other upper layer parameters such as PPP, IP, and so on should be configured under the Ethernet interface. "
So I'm thinking we don't need a Dialer interface - especially as ppp it says is configured under the (virtual) Ethernet interface.
The CCO thread says you do use a Dialer :-

This is another good CCO doc and on p.50 the Multilink PPP example is the best I can see for a VDSL (Ethernet) example.

In our case it is a private connection in a closed user group.
The BT default vlan id is configured, 4094.
We use a static IP as there is no negotiation with the carrier (they provide VPLS as a L2 service, remember) and we control the IP schema.
So I'm not clear if I need either of the following ;
== without Dialer ==
int eth 0/1/0.4094
enc dot1q 4094
pppoe enable
encap ppp
ip address a.a.a.a n.n.n.n
no shut
== with Dialer ==
int eth 0/1/0.4094
enc dot1q 4094
pppoe enable
! or if not, try pppoe enable group global
pppoe-client dial-pool-number 1
no shut
!
int dialer 1
encap ppp
ip address a.a.a.a n.n.n.n
dialer pool 1
dialer-group 1
no shut
