    • BGP routers relay messages to neighbors about routes

    • Routes are constructed hop-by-hop, beyond the originator’s
      control

coordination

  • Local policies for accepting, rejecting and propagating routes

  • This is good: Great flexibility to support business objectives

  • This is bad: Vulnerability to bogus route propagation
