[nsp] Proper way of doing dial backup for an ethernet(DSL) link

[Ezequiel Carson]

i have used  DDR on Serials and when the primary serial is down, the 0/0
is removed from FIB and then,  0/0 poiting to ASYC interface takes place
in the FIB.

But i think that this is not possible if the eth0 never go down :)

so we need a keepalive method. :)
