[c-nsp] two bgp sesion on one router

[harbor235]

Depends, if the two ISP peers were located at two different POPs and your
layer one connectivity
was diverse this would help your AS in more failure scenarios than a single
threaded design. Of course
I would also diversify the connections onto different linecards/slots as
well.
