Sam,
I also took a look at this section and wanted to make sure my understanding is
correct.
If I add the summary route to the interface then remove both floating static
routes, then
I am left with the null default route, however I do not see the administrative
distance on the asa,
when I issue a show route.
I wanted to know one could verify the AD of the summary route by looking in the
routing table or
is the interface command for the summary address the only way to make sure?
Thanks,
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
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
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, H - NHRP, l - LISP
+ - replicated route, % - next hop override
Gateway of last resort is 192.168.103.10 to network 0.0.0.0
D* 0.0.0.0/0 [90/28416] via 192.168.103.10, 00:17:44, FastEthernet0/0

WorkBook 1 Task4 point 5 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. -------------- next part --------------
