I am interested in how you measure the threat of attacks against
routing protocols against that of something like slammer, as I
would think that routing problems would limit their own propagation

I am taking sophisticated routing attacks to mean specific protocol
exploitation, instead of attacks on the devices themselves. I would
even suspect that it is not possible for routing information to be
scrambled in any widely propagated and irrepairable way, for similar
reasons to why it can't be kept straight without constant updates.
That is, the routes confusion will limit it's own propagation
precisely because it may no longer know how to propagate itself. Or
rather, the more valid paths valid routing information has, the more
likely it will spread, no?
I wonder how you could test that.
