And worse, there is no elegant way to write this policy. I.e. it's not
possible to say
         
         from {
              bgp-source ebgp;
         }
         then {
              next-hop self;
         }

because the condition "bgp-source ebgp" does not exist. You have to
fiddle around by setting colors or such on the eBGP sessions and then
check ingfor this. Ugly, and error prone.

I can name some. Most networks (by number, not by deployed routers)
don't have a full lab setup where such issues can be seen before
deployment.
