We, for example, connect to RS's more selectively.

We are more liberal about RC's since they do not have an impact on our
forwarding paradigm, and it helps the exchange point know what's
happening across their fabric. But yes, I do imagine that interest level
of connecting to either an RS or RC could vary, particularly the larger
of a network you are.

Well, there are a number of peers that do not have a linear peering
relationship for all routes available at an exchange point, i.e., they
don't see those routes both via the RS and bi-lateral sessions. For many
networks, RS is the true source and bi-lateral sessions are not even
considered.

We may not always peer with an RS, but we will always have bi-lateral
sessions... even when we have sessions to the RS.

Mark.
