Ip Route to NULL0?

We received a Router from an ISP and they have the Following Line in it.
ip route A.B.C.0 255.255.255.0 Null0 254 permanent
Where the local Ethernet Interface is: A.B.C.1 255.255.255.0
What is the Purpose of this? If the Ethernet interface is Down, route all
traffic to NULL?
Thanks,
Scott
