they are good core devices. you connect to them via a Java base program called CTC. I am supprise that it does not support EIGRP. they also use a special console cable that needs to be ordered specially for that device to connect to the TCC cards. you can connect to the ML cards via reverse telnet, so if your ML card was on slot 17 you would type "telnet 192.168.1.1 2017", to reach the IOS on that card. I'm Still learning about the devices.
