[c-nsp] MPLS route reflectors

[Mohammad Khalil]

Hi all
I have MPLS network with OSPF as the underlying IGP , my current two route reflectors are ASR9010
The
 current design is in-band route reflection , what am trying to 
implement is to pull out these two routers and use them as MPLS PE and 
change the route reflection model to out-of-band
So , I want to use lower series (as am going with out-of-band)
what are the most appropriate model/series to use/deploy?
Thanks
BR,
Mohammad
