Figures. As with essentially everything in BGP.

Oh yeah, the AS healing wars.
I didn't realize gated ever implemented this; I do
remember the first time AS path prepending met gated,
though, and a certain Russian and a certain Swede plotting
to build Sprintlink's backbone on top of ANS's using AS
healing. --:)

Oh certainly. I can think of three applications right
now, actually, where that would be the easiest (but
probably also the most dangerous) approach to solving
routing awkwardnesses.
I take it this feature is documented in the usual place?
