Yes. Suppose that I am "M", and I have two providers "A" and "B". The
links M/A and M/B are expensive international links, much lower bandwidth
than I would like, and prone to congestion. Further suppose that A is a
customer of R, and B is a peer of R. For load balancing reasons, I would
like R to send some of my traffic via A and some via B. Since I pay A and
B for transit, and A pays R for transit, and A and B both agree to play
along with my desire to load balance, it's reasonable for us to ask R to
do this. From R's point of view, their customer A and their indirect
customer M have asked them to treat peer routes (via B) and customer
routes (via A) to destinations in M as being equivalent.
