What is the advantage of BGP confederation implementation compared to BGP route reflector implementation?
A. Confederation allows use of template session and template policy. Route reflector can use only peer-group.
B. Confederation provides better redundancy. Route reflector clients can peer to only one cluster.
C. The IBGP policies can differ internally within and between subautonomous systems.
D. Confederation is more scalable. Route reflector implementation still requires confederation to eliminate completely the full mesh requirement.
