   Hi LB…

   I wonder, if my laptop can handle this huge topology. Iam using idle-pc and other gns3 features. My laptop is: Core 2 Duo 2GHZ, 3GB RAM L2 cache mem win xp.

   I am afraid that it can not handle all those routers working at same time.
   thanks

   @M.Elhassan I’d say dont wonder and give it a shot See how it works out. If it doesnt then you know your next step.

   Yes,I too believe that 6.0.1 has a bug on it. It is shuting down on my all the time, I have difficulty saving my labs.

   I think i will downgraded today.

   With respect of handling this lab, start your topology and once is running. Open the Windows Task Manager. go to the processes tab and sort of out by image name, select dynamips process. right click on it, from the menu, select set affinity, and uncheck cpu 1. repeat this procedure for every instance of dynamips you find running on your pc.

   LBS - Thanks for the lab - saved me heaps of time putting together a test lab from scratch.

   However, there’s a bug: The virtual link doesn’t work (nets 1.1.110/24 - 1.1.113/24 don’t show up)

   The virtual-link command takes the area id of the TRANSIT area, so on R3 it should be:
   router ospf 3
   area 4 virtual-link 1.1.113.1 !NOT area 6 vir….

   and on R11:
   router ospf 11
   area 4 virtual-link 1.1.33.1

   Thanks again
