  I was going to make that point -- that is, I would not
expect to see:

> O IA    172.16.0.3/32 [110/11] via 172.16.2.1, 04:31:29,
FastEthernet0/0

...(although I could be wrong -- I don't get many looks into
CPE).  Also, I'd expect the sham-link neighbor to show up on
the PE.  You can see them on Cisco PEs, for instance:

CiscoPE#show ip ospf [process] neighbor

Neighbor ID     Pri   State           Dead Time   Address   
     Interface
[...]
[Remote ID IP]    0   FULL/  -           -        [Remote LB
IP]  OSPF_SLn
[...]
CiscoPE#

...so there's no confusion as to the state of the sham link.
 I don't have a Juniper L3 VPN PE or a Cisco CE handy.
