[c-nsp] Routing Question

Hi Everyone,

I am wondering, is it possible to route traffic based on the Source IP to
specific BGP learned routes?  For instance, if I have IP Range
2.2.2.2/24that I want only to use routes learned from peerings with
say AS 444, 555,
666.  But I want to have IP Range 2.2.2.3/24 use the routes learned from
peerings with say AS 111, 222, 333.  I know I can do PBR and set the
next-hop based on the source IP but it appears that even with multiple
entries in that route-map statement it will choose one out of the list and
use that by default and not choose the best path learned from the neighbors
I want it too.  Can this be done with local-prefs or weights?

Thanks

Joe
