[techtalk] setting up virtual interfaces on linux

[Arindam Chatterjee]

hi 
i am running linux on my machine which is not
connected to any network. it doesn't have any
interface card on it. but i want to do some network
programming on it. i want atleast three different
networks configured. is this possible by configuring
virtual interfaces? if i send a packet from one
network to another will it travel through the whole
protocol(TCP/IP) stack or just go through loopback
interface(lo)? this is required, because i will be
working on protocol independent multicasting(PIM). i
want my computer to work as a router which is
connected to three different networks through three
interfaces(virtual if possible). i have the pim
routing daemon which will do the job of routing. i
only need three interfaces(eth0, eth1, eth2) without
connecting my computer to any network and without any
interface card inserted in it. i hope u got my
problem.
pliz help me ASAP.
