A housing authority must scale iBGP so closet PE routers do not require a full mesh to every other iBGP speaker. What is the primary purpose of deploying route reflectors?
Select an answer to reveal the explanation.
Short Explanation
Full-mesh iBGP is every closet calling every other closet—n squared phone lines. A route reflector is the switchboard: clients peer with the reflector, and it passes the routes along. Same iBGP rules, way fewer sessions.
Full Explanation
BGP route reflectors allow a hierarchy in which clients peer with reflectors that advertise learned iBGP routes to other clients and peers, avoiding an n² full mesh. They do not remove the need for IGP reachability to session endpoints, nor do they turn iBGP into eBGP by default. OSPF cannot replace Internet-scale BGP tables. Use reflectors for iBGP scalability inside the civic ASN.
