Re: OT - Fridays Puzzle

OK, the answer:

When configuring IP default-network you can reference a major network or a
subnetted network.

If a major network is referenced, and the network that you are referencing
in the ip default-network command is advertised, it goes out as the
candidate default.

If a subnetted network is referenced, the IOS will inject a static route in
your running configuration, and this was the behavior that I was looking
for. BTW, the network will not be advertised as the candidate default.

Therefore, the answer to the puzzle is:

Ip default-network 2.2.0.0

Router eigrp 100

  Redistribute static
