Please check my previous reply on the logic of use since there is a floating
static default with AD of 222 for outside-2 interface.
You do not need prefix list
interface GigabitEthernet0/1
authentication key eigrp 111 CISC0I123 key-id 10
authentication mode eigrp 111 md5
summary-address eigrp 111 0.0.0.0 0.0.0.0 250
NULL route is similar to a discard route and is locally significant on that
router which advertises EIGRP default route or uses summary address in
eigrp. Here we are referring to the AD of the NULL route and not the AD of
the advertised route which R1 receives.
See below R1 has the default route but the AD is the default of 90. Hence
what we are taking about is the AD of the NULL route generated when
summary-address command is used on ASA which is locally significant.
R1#sh ip ro

Hi,
I do have some questions in regards to that specific point. It says that I
need to send the default route to Router 1 (Which I already did to practice
prefix lists :)) but it also says that change the distance of the null route
to 250 and that is where I get confused.
Is the null route the default route? Also, is that route the same one that
it is being advertised? I saw that I can change the distance, but only for
routes inserted on our routing table.
Was looking also for the DSG of Workbook 1 but it seems like it is not
finished already.
Thanks,
Mike.
