Nnanna,
Beginning in 11.2 IOS, inbound route-maps filtering on IP address actually
had an effect on the updates. Before 11.2, the statement from the BGP paper
that you refer to was true.
Check out the 11.2 release notes under BGP4 enhancements (Watch wrap):

BGP4 Prefix Filtering with Inbound Route Maps-This feature allows
prefix-based matching support to the inbound neighbor route map. This
feature allows an inbound route map to be used to enforce prefix-based
policies.
I have also tried this in the past with 12.x code and filtering works fine.
HTH,
-Chris

This BGP paper on the cisco website states that :
Route maps associated with the neighbor statement have
no affect on incoming updates when matching based on
the IP address:
I have always been able to filter incoming updates
using route-maps...indeed I have a working config as I
speak...Does any one have an explanation for this? Am
I misunderstanding something?
cheers
