Moving BGP into the IP Base feature set is a recent change.

Yes. Although I wouldn't necessarily use 12.4(24)T, the latest maintenance
build of 12.4(15)T should be more stable.

It's my understanding that you can download any software of the feature set
you're entitled to use if you have SmartNet.

Hope it helps
