Enterprise Router R1 connects an Enterprise to the Internet. R1 needs to create and
advertise a default route into the Enterprise using EIGRP. The engineer creating the
implementation plan has chosen to base this default route on the ip route command, rather

than using ip default-network. Which of the following is not a useful step with this style of
default route configuration?

A.
Create the default route on R1 using the ip route 0.0.0.0 0.0.0.0 outgoinginterface
command.

B.
Redistribute the statically configured default route.

C.
Disable auto-summary.

D.
Configure the network 0.0.0.0 command.

E.
Ensure R1 has no manually configured summary routes using the ip summary-address
eigrp command.

Explanation:
With the suggested configuration style, the static route must first be configured statically, as
shown in answer A. Then, either this route must be redistributed as a static route into
EIGRP (answer B), or pulled into EIGRP by virtue of the network 0.0.0.0 EIGRP
subcommand answer D). The other two options have no effect on default route creation and
advertisement.
