5.9 BGP Configuration Examples

5.9.1 Configuring BGP Confederation Attribute

I. Network requirements
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 to minimize the CPU and network resources
consumption by BGP without affecting device performance.
Based on user requirements, configure a BGP confederation to achieve the goal.
