BGP Route Reflector is a BGP router that reflects iBGP routes between clients to reduce full-mesh requirements.
Simple definition
BGP Route Reflector is a BGP router that reflects iBGP routes between clients to reduce full-mesh requirements. It belongs to the Networking vocabulary.
What is it used for?
Its main purpose is to scale an iBGP domain with fewer router-to-router sessions.
How does it work?
it applies iBGP reflection rules and attributes such as Originator ID and Cluster List to prevent loops.
Key points
- Scope: A BGP router that reflects iBGP routes between clients to reduce full-mesh requirements.
- Operational goal: Scale an iBGP domain with fewer router-to-router sessions.
- Mechanism: it applies iBGP reflection rules and attributes such as Originator ID and Cluster List to prevent loops.
Points to watch
Poor cluster design can reduce route visibility or create suboptimal paths.
In short
BGP Route Reflector is a Networking concept to know when you need to scale an iBGP domain with fewer router-to-router sessions.
