PfR relies on an iBGP session between the Border Routers for route control.
This is usually not a problem because the pair of routers facing the
Internet or WAN running eBGP will usually already have an iBGP link to each
other (with or without PfR).

PfR runs at the edge routers and does not need to be enabled everywhere
through your core.
