Hi,
The "default-information in/outo - This command is NOT the same as in
OSPF or RIP, as RIP & OSPF let the local device ORIGINATE a default
route. The command in EIGRP allows the control of a DEFAULT ROUTE
only.
There are few ways I can think of generating a default route in EIGRP
1) "Summary-address"
(interface) ip summary-address eigrp 100 0.0.0.0 0.0.0.0 5 o applied
on an interface, so a default summary route is sent to the
corresponding neighbor. Also, take note that the route creating this
summary-address also creates a "discard route" in the routing table to
NULL0
0.0.0.0/0 is a summary, 00:02:01, Null0 o - by default
This also happens in OSPF when doing a area range/summary-address, but
you can remove it with the "no discard route internal/external" Under
EIGRP application of a floating distance removes the null route from
the table.
2) "ip route 0.0.0.0 0.0.0.0" + "redistribute static"
ip route 0.0.0.0 0.0.0.0 null 0 o - creates a static route
redistribute static metric 10000 10000 255 1 1500 o -redistributes the
static route into EIGRP as an external route with an AD of 170
Also you must specify the metric when redistributing with EIGRP.
Remember you can't create static routes in the exam.
The "ip default-network X.X.X.X"
The network being flagged as a default must be a CLASSFUL network. Any
routes not known will be sent towards this FLAGGED default route. If
you flag a subnet (non-classful network) you will see a static route
appear in the config, this is not what you want.
If you DO NOT have a classful network in your routing table to point
the "default-network" command to. Create a summary route on the
upstream neighbour to advertise a CLASSFUL network down to you then
try the command again.
