Hi ,
Pls take a look-
The BGP PA feature is first supported by the following platforms that support Cisco IOS Release 12.0(9)S.
Cisco 7200, 7500, and 12000 Series Routers
The number of platforms that support this feature in Cisco IOS Release 12.2(13)T is much larger. The platforms include:
1400, 1600, 1700, 2600, 3600, 7100, 7200, 7500, AS5300, AS5350, AS5400, AS5800, AS5850, ICS7750, IGX 8400 URM, MGX 8850, uBR7200.
From this link
http://www.cisco.com/warp/public/459/38.html
I spent 2 or 3 days trying to configure accounting on a cisco 6500 box and concluded it is not supported.
May be someone else throw some light on this mystery.
Thanks
Mohamed.
