[c-nsp] Optimal solution for iBGP mesh

[Kanagaraj Krishna]

Hi,
   As we all know, fully meshed iBGP topology is not suitable for network 
scalability. The recommended alternatives are route reflector and AS 
confederation (we are practising the former to a certain extent). At the 
moment we are thinking of having a few (maybe 2) routers just dedicated as 
Route Reflectors but the load on this routers would be high. 
Just curious whether, MPLS can be used in the same way to reduce BGP sessions 
and processing load on network equipments?

- Maybe have internal routers using next-hop labels to direct traffic to edge 
routers. 
- Meanwhile only internal routers connected to downstream BGP customers are 
configured to receive full routes.

Please advise whether this option feasible. If there some of you guys/gals who 
are using a similar setup please share additional info on how to get it up and 
running (article, reference etc). Thanks.
