Those interfaces don't to auto-negotiation at all.  That's why they 
default to 100 half.  OP said they were using a Gig interface though. 
Maybe a copper 10/100/1000 port on an NPE-G<1|2>?  I haven't used those, 
but I'd bet they support auto-negotiation.  1000baseT requires it.

It'd be helpful to know how they've tested through the router, and if 
there are other connections routed through that VXR that are working at 
the expected rates.
