[cisco-bba] VPDN Vendor-Tag (Circuit-id)

We have a CISCO 7206 acting as LAC (running 122-31.SB9) for PPPoE
Sessions comming from a Ethernet based DSLAM (ZHONE MALC). We run one
VLAN per DSLAM and collect the session via Gigabit SubInterface (the
vlan range command didn't work at all).

Now I would like to transfer the Vendor-Tag ID's (Circuit-ID AVP 87 ) to
the LNS. Unfortunately it didn't work out .. has anyone a hint ?
