Hi Ali,
Take a look at
http://www.internetworkexpert.com/resources/iosonpc.htm There are some
dynagen .net mappings that I use for R&S and SP topologies that you can
download along with step-by-step instructions on how to load it. The SP
topology includes 7200s running 12.2S and 3600s running 12.3T. All you
need to do is search CCO for those specific image names, uncompress
them, and run the dynamips process.
For ATM PVCs there are mappings to the built in Dynamips ATM
switch emulation process. For Cell Mode MPLS over ATM there are
mappings to a preconfigured 7200 router instance that MPLS switches the
ATM cells.
As for the hardware to run it I would recommend a minimum of 2GB
of RAM and a dual-core processor. The reason for the dual-core is that
you can send the dynamips processes to the second core only, that way
when they eat up 100% of the CPU (which they commonly do) you're still
at only 50% overall utilization.
Recently I switched from Windows XP to Mac OS, and I have
Windows running as a virtual machine inside Parallels. The nice thing
about this is that when Dynamips boots inside the Windows virtual
machine it can take 100% of the CPU of the virtual machine process, but
still never 100% of the physical processors. You could probably get the
same effect by running Windows or Linux inside VMWare and booting
dynamips from there.
HTH,

Subject: SP Track using Dynamips
Hi all,
Just starting my preparation for CCIE SP, want to setup SP lab using
Dynamips. I would appreciate if someone can recommend me the
specifications
of system like RAM, CPU etc..also which images to use (I have some
scattered
stuff, need a summary list if someone has already set it up), what is
the
alternate of the ATM switch?
Also can you simulate full SP lab using dynamips or there are some
short-comings as compared to the required hardware?
Thanks in advance
Regards
Ali Sheeraz Mehdi
