8.28.5 Example for Configuring BGP Routing Policies

BGP routing policies can be used to flexibly control traffic on a complex network.

multimedia services, signaling services, and accounting services. Two sites, each of which has
two PEs accessing the core layer, are used as an example. MP-BGP is used to advertise inner
tags and VPNv4 routes between the PEs. Each PE establishes an MP-IBGP peer relationship
with the RR. Each PE sends BGP Update messages to the RR, The RR reflects Update messages
to the PEs excluding the senders of these messages through different planes.

NOTE
Figure 8-33 is a simplified networking diagram, in which there are two sites, one RR, and two planes (each
with three Ps). On the actual network, there are 14 sites with 28 PEs, and each plane has four Ps and two
RRs. Each RR needs to establish MP-IBGP connections with 28 PEs.
