In the real world, and even in the lab if you don't want long periods 
of doing nothing, do remember that the default RFC timer values are 
far too long to be useful. Look at what you are doing, and set them 
to a much shorter interval.

To review, there are several IPv4 ways of finding the active (if 
there is more than one) local router, of which IDRP is one:

IDRP (can get a list of routers).

DHCP/static configuration with HSRP, including overlapping groups if 
supported (probably best way to load-share)

Passive RIP (I suppose you could use other routing protocols in 
passive mode, but I've never seen it done in the real world -- nor 
can think of a very good reason to do it).
