[nsp] BGP routes received but not used

[Jared Mauch]

	You also need to watch out for the translation stuff, nobody
at cisco spent a lot of time testing it and i've found numerous bugs and
has them fix them over a long period of time.  You will also want to get
some more recent software for multicast, because older versions (for quite
some time) were unable to redist connected -> mbgp.

	This was fixed after 6-9 months of constant nagging on our part.

	Beware, as that same code base is now in 12.0S and may cause
heartburn and ttl expired packets.
