Hi Tarik,
When installed in the routing table you can see the admin distance. Samarth Chidanand Sr Instructor / Developer - IPexpert CCIE #18535 (R&S, Security) CCSI #34585 From: [email protected] [mailto:[email protected]] On Behalf Of Tarik Admani Sent: Tuesday, May 21, 2013 7:21 AM To: [email protected] Subject: [OSL | CCIE_Security] WorkBook 1 Task4 point 5 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.

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 -------------- An HTML attachment was scrubbed...
