Hi Everyone - I am new to this list, so here is my first post. I am studying for the CCIE sec lab, and have completed the volume 1 workbooks. I am now on lab 1A, objective 1.5 on the updated material - configure SLA monitoring for the default route to R2 (192.1.24.2). I configured the SLA monitoring as per the proctor guide, configuring the backup route to 192.1.24.4 with a distance of 5 and noticed that when I shut the interface on R2, that the route to R4 was not coming up. Instead I was getting a Null0 route created by eigrp to 0.0.0.0 0.0.0.0. I removed the eigrp summary address command from earlier in the lab and the route appeared correctly. Then after doing a show run I noticed this -
interface Ethernet0/0.7 summary-address eigrp 200 0.0.0.0 0.0.0.0 5 My summary address also had a distance of 5 - put there by the IOS - I did not specify this. When I made my static backup route to 192.1.24.4 with a cost of 4, it worked! Did anyone else notice this?? One to look out for.....
