The above display shows that sub-AS routing information is advertised only within the
confederation. A device in an AS outside of the confederation, such as Switch E, cannot
learn the sub-AS routing information within the confederation because it treats the
confederation as a single AS.
2.1.7 BGP Route Reflector Configuration Example
I. Network requirements
1) Requirement analysis
BGP runs in a large AS of a company. As the number of IBGP peers increases rapidly in
the AS, more network resources for BGP communication are occupied. The customer
hopes to reduce IBGP peers and decrease CPU and network resources consumption
of BGP without affecting device performance. In addition, IBGP peers are partially
interconnected in the AS.
Based on the requirements and networking environment, configure a BGP route
reflector to achieve the goal.

Figure 2-7 shows the network diagram.
