It can be done but you must be careful not to cause routing loops. IMHO it is best avoided unless you are conversant in IP networking and know how to use the right tools to troubleshoot if you run into problems. It can even be useful for redundancy and bandwidth sharing purposes, which is where things like STP (spanning tree protocol) and RIP come into play but I wouldn't recommend it to a networking novice.
You are talking about routing protocols. This would be true if you used
the 2 NICS for routing. But, simply having 2 NICS each with a separate
IP address on the same subnet is not going to cause a problem. I
sometimes do it on one of my laptops by having both a wired and
wrieless working. If you are using simply static routing, there should
be no problem. But, you really don't get much (or any) benefit unless
you want the redundant bandwidth. But, I have never seen a routing loop
caused by a simple routing table in an end-user machine.
