Hi!

And one minor comment:

In section 3 and section 6 it says:

“For the sake of scalability the advertisement of multiple paths should be limited to those prefixes which are affected by MED-induced route oscillation in a network carrying a large number of alternate paths.”

How do the RRs or confederation ASBRs identify those prefixes affected by MED-induced oscillation?  Is there some rules or it is operator configuration?

The oscillations are described in rfc3345.  However, the implementation of an automatic mechanism may not be trivial, and it is outside the scope of this document.

Thanks!

Alvaro.
