BRAS Config for MPLS carrying PPPoE

[william jackson]

       Hi all

DSLAM----(PPPoE)---7600----(Xconnect)----7600----(VLAN/PPPoE)---(BRAS ASR1K)

we currently have a distributed access network where the DSLAMs send us PPPoE packets which we are wrapping into xconnects back to a central BRAS.

the xconnects terminate on the upstream device to the BRAS.  The BRAS is connected by a VLAN trunk and each DSLAM is identified by a unique VLAN-ID.

so the BRAS gets native PPPoE frames.

I wish to extend the MPLS to the BRAS itself.   So that the xconnect ( or VPLS ) terminates on the BRAS itself.

I cant see how to stitch in the PPPoE features to get this to work.

I was thinking about an external looping cable on the same BRAS device but thats a bit crap

Is there a more elegant solution?

many thanks

Hi,

You can try pseudowire headend configuration. But I am not sure its avaliable for AS1K.

Hi, it seems that PWHE is available only for ASR9000 and CRS1. I saw it in the IOS feature navigator.
