- Careful: ripquery is not to be trusted, precisely because it does *not*
- truthfully show the routes that are being rip-advertised. ripquery operates
- by generating a rip POLL, which explicitly asks the queried gateway to say
- what its rip-list looks like. Unfortunately, most machines ignore
- split-horizons when they respond to a rip POLL, so what you'll see is a
- list of *all* the advertisements that gateway is making, regardless of whether
- or not it will make them onto the network that you're querying over.
-
- The only way to really make sure of what advertisements a gateway makes is
- to sit and listen for them, e.g. with gated tracing turned on or some
- handmade NIT utility.
