Sounds like I better damn well know how to use BGP inject-map. Thanks

	Support starts at 12.2(4)T, and the platform support is more than
the 7x00 as stated.  It's no secret that there is a 3700 series router in
the lab now.  Regardless of whether or not the other routers are running
12.2 mainline or 12.2T, if you take a look at the software center you can
see that the 3700 supported 12.2 IOS is:

12.2.15T9 (ED)
12.2.15T8 (ED)
<snip>
12.2.11T (ED)
12.2.11-YT2 (ED)

	In other words, the 3700 will be running at least 12.2(11)T.  What
does this imply?
