Haaaahaha :-)

What you *can* do is drop all routing headers, but then you break
Mobile IPv6.  Which nobody is using.  

OTOH, using control plane policing, policing packets with RH headers 
targetting your routers down to "100 pps" *should* definitely reduce the 
usefulness of RH0 attacks using these routers as "bounce point" - if it 
is properly supported, which I'm not 100% sure right now.
