IE OEQ Question...

I came across a question posed by the IE OEQ simulator that had something like this output displayed:

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

     172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
C 172.16.1.0/24 is directly connected, Loopback10
D 172.16.0.0/16 is a summary, 00:00:39, Null0
     10.0.0.0/8 is variably subnetted, 6 subnets, 2 masks
C 10.50.50.0/24 is directly connected, Loopback4
C 10.40.40.0/24 is directly connected, Loopback3
C 10.30.30.0/24 is directly connected, Loopback2
C 10.20.20.0/24 is directly connected, Loopback0

And it asked what the router would do when destined to 172.16.2.0...

The answer provided said that it would be dropped due to a static route to Null0 or something like that. The wording definitely specified "static".

My answer was the packet would be null routed which means it will be dropped.

I understand the necessity to explain what configuration caused by the route to Null0. This one is caused by an EIGRP summary address configured one the interface, not a static... Does anybody know why this route might be considered a static?

Thanks,
