QuestionQ104

Routing Policy and Manipulation

What is the purpose of a BGP confederation?

  • A It reduces the number of iBGP peers and increases stability
  • B It improves service by increasing the number of simultaneous iBGP peering sessions
  • C It redirects traffic away from route reflectors, which reduces their operating load
  • D It limits the number of routes a device receives from its peers, which reduces CPU load
Explanation

A BGP confederation partitions a large autonomous system into smaller sub-autonomous systems so that iBGP does not require a full mesh across every router. This reduces the number of iBGP peerings needed and improves scalability and stability.
