Hey All,

Thank you for the awesome simulator. I wish that i can help get the 3550 switch & 6500 switch emulated. is there anyway i can help Chris & Greg as i truly believe this product is awesome and would like to see layer 3 switches in dynagen/dynamips.

cheers,

Hi Chris!

First of all, congratz about the dynamips project.

Regarding the Cat6500 SUP1A access. I can provide you access to one during two weeks about the end of march.

Are you still interested?

Keep up the good work!

To compile dynamips under cygwin, just set the HAS_RFC2553? variable to 0.

You need to install libelf (not available thru setp.exe).

Valpa,
Here is a link to the IPv6 extensions for cygwin: http://win6.jp/Cygwin/
You will also need libelf: http://www.mr511.de/software/

from dynagen configuration file:
mmap = true # Set to false to use real memory rather than a disk file for router vitural memory. Conserves RAM at the expense of performance. Defaults to True

Easy solution: Create a ram disk, make the ram disk your working directory then start dynamips etc from there.

Hi Chris and Greg,

I cannot compile dynamips on my cygwin environmnent because of inet6 problem. There is the error:

net.c: In function `n_ipv6_ntoa’:
net.c:84: error: `AF_INET6′ undeclared (first use in this function)

It seems that cygwin do not support IPv6, but I found in cygwin website that IPv6 was already supported. Unfortunatly, I do not found *any* version of cygwin with AF_INET6 and PF_INET6 enabled in socket.h.

Hi Chris and Greg,

I really appreciate this wonderful tool that you have created.

I am experimenting with a few things on how to make the simulation quicker. The topology I am working with is the Internetwork Expert CCIE R&S and SP workbook configurations.

I think that the emulator can work significantly faster if the number of files created by simulator is reduced (the various files such as C3600_R1_log, C3600_R1_nvram, bootflash, Ghost image files etc.) While acknowledging that there are valid reasons for creation of these files, Is there a flag that I could use to disable creation of all these files on the hard disk or keep the files in RAM only and do away with the disc access times. I am sure a RAM only option though either an increased need for RAM or lesser number of Routers being emulated in a Given RAM scenario will be fine.

Of course in Real routers, the actual files are on flash and there are no disc accesses and hence the real routers are significantly faster and can processes higher throughput.

Please let me know your thoughts.

Regards

Rama
