Hi,
My Email didn't reach the group. Just wanted to post some more tips about
the emulator,

Onderwerp: RE: 7200 router emulator
Hi,
Some people have trouble to get the routers communicating with each other.
I've seen this at my pc also:
- Start the routers up sequentially, not parallel.
- If you start one up, check with netstat -na (windows) if you see a mapping
to 0.0.0.0:100001 or whatever UDP port number you use. If you start your
second router check for another mapping to the other UDP port, e.g. 10002.
Sometimes the UDP portnumber is not mapped correctly. If you don't see a
"mapping", use other ports, that helped for me.
- After the routers are booted, and you've configured ip addresses it takes
some time before you can ping your neighbor. You can check the CDP table if
you've got CDP neighbors on both sides. If you've got CDP neighbors on both
sides the UDP ports are mapped ok, and sending ICMP packets should be fine.
- I've been playing around with the -r (allocate RAM) to see what happen.
128 MB will start up but works slow, the default 256 MB is ok, but
allocating 384 MB of RAM seem to work better when the routers are booted
Regards,
Henk

Henk, how did you make the two routers communicate? I tried to play with it
but i couldn't ping the ethernet interfaces even with ip addresses only
configured on them.
dynamips -t npe-400 -p 0:C7200-IO-FE:udp:111:127.0.0.1:222 C7200-IK.bin
dynamips -t npe-400 -p 0:C7200-IO-FE:udp:222:127.0.0.1:111 C7200-IK.bin
Thanks for sharing this information. Great program :)
Regards,
Ridney
