Hi,
The guy from the site simulates a 7206, so six slots are available for use.
You can put the module PA-FE-TX in slot 2 to 6 ending up with six
fastethernet interfaces. Just map the UDP portnumbers to each other and
you'll be fine.
Yesterday I setup three routers. Two routers connected to one (hub and
spoke). One the hub I created a bridged group and a BVI with an ip address
so It looked like there was a switch in the middle. Nice for testing RIP
broadcast/unicast setups etc.
Also don't forget you can fire up an atm interface in the config as well,
along with a virtual ATM switch in the middle. Download the source code from
the site and open the readme file, you can find everything in it.
The only bad thing is that is is very slow with three of four routers, is
takes about 15 to 20 minutes to start up the routers. With two routers It's
much better.
Regards,
Henk

Onderwerp: Re: 7200 router emulator
Hi,
is it possible to emulate more than one FE interface? (and build up mesh of
7200 routers network through FE interfaces)
