[c-nsp] OSPF+BGP and MPLS Q's

[ringbit at mail.com]

Hi all,

I have some practical design questions.

1. Is there a better way of doing the HA than having adjacencies to the router (can be 3 hops away) over two different VLANs and different OSPF cost over trunk links with BFD enabled? 
2. Do you find less practical a MPLS network on a multi-area design vs a single-area design?
4. At what point would you introduce RouteReflectors in the network (e.g. when 5, 10, 20 IBGP connections?)

Can come up with some more in the meantime ;)

Thanks!
