[c-nsp] IS-IS: Ignore Attached Bit

[Shankar Vemulapalli (svemulap)]

Asbjorn -  This is useful in the case of L2-->L1 Route-Leaking where you
*may* not want L1-Router to use its
default to point to L1L2 router and L1L2 end up in dropping the traffic.
With Route-Leaking, L1-Router does
get the specific routes.   This way, for any traffic that L1 doesn't
know, it will drop itself rather than 
sending to L1L2 and then L1L2 dropping it.   Hope it is clear.
