asked on

process for selecting an exit interface

A colleague asked me this. He has a w2k box with two nics and a modem all actively connected to an ISP. If he does a telnet session to a remote IP, how is the exit interface determined? Another words, does a broadcast get sent out all interfaces initially or does one NIC or the modem connection take priority somehow?

It acctually has nothing to do with metrics, if you attempt to to a telnet to a remote IP you machine looks at the IP address, if it does not reside on you local network it will send it to its default gateway, the gateway will then determine if it has a path to the network if not it will send it to it default gateway, when you do a route print you will see
Active Routes:
Network Destination Netmask gateway Interface Metric
0.0.0.0 0.0.0.0 192.168.0.126 192.168.0.254 20

what the 0.0.0.0 basically means is "for all unknown networks send to the gateway"
