[j-nsp] bgp path

[David Ball]

  Hi Dan.  The default action depends on whether it's an import or
export policy, and on what protocol is being used.  For all import
policies, the default is to 'accept', so the 'then accept' isn't
really needed, but personally I like to see it for my own sanity.  See
the following link for a list of protocols and their defaults if
you're interested in a particular combination:
