Having each peer in its own group is one of the best ways to shoot
yourself in the foot: instead of all peers with same egress policies
share RIB-Out, in this model each one will have its own RIB so memory
use will go through the roof.. (well, at least in SP scenario, where
most peers need to keep full-view in RIB).
