QuestionQ23

VPN Architecture

In a typical service-provider environment, which two tools help scale PE router connectivity requirements?

Choose two
  • A route reflectors
  • B VPNv4 address family
  • C originator ID
  • D cluster ID
  • E confederations
Explanation

Route reflectors reduce the full-mesh iBGP peering requirement among PE routers. BGP confederations improve scalability by partitioning a large BGP autonomous system into smaller internal sub-autonomous systems while presenting a single AS externally.
