Remarks
Optional.
By default, an RR does not filter the
reflected routes.
With an RR reflection policy, only
IBGP routes whose Extended
Communities attribute matches the
specified one are reflected.
By configuring different RR
reflection policies on different RRs,
you can implement load balancing
among the RRs.
