Dear All ,
I am using Dynamips (with 3GB RAM , 2.2 Core2Due ) and
trying to run the full IE lab on it , i can load all 14 devices with
cpu load less than 5%. I can do Switching , Framerelay, RIP , EIGRP
with less than 50% CPU load but after OSPF and Redistribution it is
going up to 80% and at that time if i tried to show the running config
processor reached 100% and framerelay , ospf come down & up. At that
time i have more than 1 GB RAM as unusable. So have tried to change
the idle pc value but no use.
All these are happening in Windows XP , So i want to know is it
possible to customise or do i want to try withh Linux.
Regards,
Anbu.
