Jeff,

I am somewhat late in chiming in on this thread, but I'm also supportive of
> making this a MUST.

​As discussed before I disagree. Injecting AS(es) is a simplest form of
making some paths less preferable then others. ​And per peer policy asking
RS send my paths to peers X,Y, Z with + 4 ASes, but to peer A, B, C do not
prepend as Niels points out maybe there already today.

​To me the Route Server is a Route Reflector for EBGP sessions. It really
does not matter if you are messing with AS_PATH there or not. What actually
matters ​is that you do not set next hop to yourself there.

Cheers,
R.
