Hey Rick,

I am trying it on some different models: 6500, 7600, and a 3640, haven't
tried a 7200. All of them behave the same way. When I remove the VRF and
just have a normal EBGP session, it works. I might have to peer the Trigger
router one hop away from the PE (multihop EBGP, while sharing the peering
address through the VRF), I have tested this and it seems to work.
