[c-nsp] 7204VXR NPE G1 Upgrade from 12.4 to 15.1M Issues

[Chuck Church]

Did you confirm that the prefixes you were sending via BGP under 12.4 didn't
disappear when running 15.1?  Are your peers still accepting them?  It's
possible a default changed that is affecting your advertisement.

I have a 7204VXR with NPE-G1 that is running 12.4.25f Advanced Services. 
This router is acting as our main connection to the internet running full
BGP routing connected to 2 providers via ethernet.  I'm wanting to upgrade
to 15.1M Advanced Services w/ LI.  After loading the router with IOS 15.1M,
the router comes up correctly, all BGP sessions come up correctly and the
routing table looks correct.  I can ping the outside world from the router.
When i try to access the internet from another station, all traffic dies at
this router.  I can ping all interfaces on the router from any workstation.
I have sanitized configs for those that would like to see them.  This is a
pretty basic setup, not doing anything fancy.  Soon as I load 12.4 back on
the router and reload, everything comes back up just fine.  Any thoughts?
