[c-nsp] BGP soft reconfiguration inbound

Hi Mohamed,

to add to what has already been said that if the BGP session with your
neighbor supports Route Refresh capability, you will still be able to
apply new policies softly - which helps overcoming the major drawback
of resetting the session thus impacting the live service. 

To check this out: "show ip bgp neighbor  <IP address>" and then look
at the "Neighbor capabilities" section.

Cheers,
Paolo
