Feature Navigator is unfortunately badly broken. To see how broken,
compare features for a 6500 Sup2/MSFC2 IOS 12.2(18)SXF16 with a 7600
Sup2/MSFC2 IOS 12.2(18)SXF16 with the same feature sets (advanced IP
services, for instance) (yes, identical versions, identical images).
The results may shock you.
This is not the only comparison that is broken; try comparing 12.4
(18c) with 12.4(23) on 7400. I trust Feature Navigator about as far
as I can throw a 12012 GSR.
Also compare the 12.2(33)SRC on the 7200 with the same thing on 7600.
Or try 12.4(21a) on 7500 with the same thing on just about anything
else.
I wish Feature Navigator worked as advertised, I really do, as it
would be a great tool in that case.
But Gert's advice is wise indeed on those platforms where you have a
choice and don't need 'S' train features.
