Can someone give an example of how to use source routing to check a peers routing policy?
Channelling from a similar private conversation I had many years ago: Seeing if packets directed to prefixes that you're not announcing come back to you is interesting (and can be an indicator that someone is pointing default at you). Seeing if packets directed to prefixes you *are* announcing *do* come back to you is also interesting. So, an example might be to send a traceroute across a peer's link via source routing, and watching the result.
