I am looking for a full feature Cisco simulator that I can use for
developing new networks. I don't really want one targeted at the
various CCXX labs and courses. Everything I have found so far seems
targeted at the student and is very LABcentric. If it does allow for
free form design, has a limited device library. About the best I have
found so far is Boson's CCNP offering which while it will allow for
some free form design is somewhat limited in it's device library (at
least the demo version is anyway).
Anyone able to recommend anything?
Thanks |

Dynamips with dynagen.
Its not a simulator, but an emulator - which is good,
and bad.
It's good since it is a real IOS router (an arbitrary number of
which you can run on a PC), but bad since you need
a real IOS image. Well only bad if you can't get one:-(
Anyone with a clue or a service contract can:-)
Obviously the number of routers that can be emulated
on a PC is resource constrained but 6 or 8 or 10
seemed OK on a dual core 2GHz x 2GB DRAM
laptop on windows (cygwin). - YMMV. I have the idea
that native linux might well be a LOT faster but have
not yet evaluated it.
There is also a graphical front end for dynagen.
gns3 looks like it, never tried it tho'.
To run a load of routers on a single PC needs a bit of care.
It's all documented. Use less exotic routers, 2600, 3600
instead of 7200, use sparse memory, use (oh I forget)
whatever they call it that allows a single code image to
service >1 router. Use 2 instances of dynamips since
unless on 64bit OS there is not enough virtual memory.
If you like use >1 computer. All beautifully seamless.
I think dynamips is single threaded so if you have dual
core you need two instances of dynamips to use
them - can't really recall that exactly either. Have
a go yourself.
Whole thing is a true WORK of ART - be in AWE.
mmap = True
ghostios = True
sparsemem = True |
