My Answer to CCBootcamp lab 1
　　Keywords: CCBootcamp answer ip local policy route-map OSPF NBMA
　　I had finished the CCBootcamp Lab 1 myself and find out that my answer is better then that one which is passing online. looking at that answer you will be wondered, according to the lab script, we should use routing but no layer 3 to layer 2 mapping to accomplish the task, but the answer provided did not.Here is my answer and some key points:
　　First, I have to introduce my lab. Because we don't have a 2509 or 2511 to act as terminal server right now, I used a 2505 instead. Each router connect its ethernet port to 2505's hub port, and configured with a secondary address of 129.1.1.0/24 as management address, It is a good idea, I can now telnet from a router (R7) to access the console, but I have to handle routing update carefully, preventing them be sending out the ethernet port, so as not to cause an 'Area ID mismatch' error.
　　Another question with my lab is that we don't have enough memory on 2522s to run a 12.1 image, so we still have 11.3 or older version run on some routers, one thing must not be ignored is you have to enable ip subnet-zero and ip classless because it wasn't the default setting.
　　As the lab script demanded, we don't use any 'frame-relay map ip' commands, since the default ospf network type on NBMA interface is non-broadcast, neighbor is manually set, with proper priority. I have to reboot some router to make R1 the DR.
　　As hints implies, we used ip policy route-map to modify the routes to give it an correct next-hop address. the policy route-map should be applied to incoming interface, for example s1 on R4 and E0 on R5. Since we testing the connectivity on the router, i.e. the ping packet is source from the router itself, we have to enable ' ip local policy route-map'.The route map must not modifying multicast traffic such as 224.0.0.5 and 224.0.0.6 for OSPF to work correctly.
　　I know my answer is far from perfect, any help from anybody is appreciated. Mail me at nnwh@163.net, thanks in advanced.
