  2. When the PE populates the route received from the CE into the VRF.
  3. When the PE propagates the route to the CE.
  4. When the PE exports the route from the VRF into the MP-BGP table.

Answer(s): D



A customer has two sites connected to PE-1 and a third site dual-homed to PE-2 and PE-3. If BGP is used as the PE-CE protocol, what is the total number of BGP and MP-BGP sessions required on PE-1 for a functional VPRN service? Assume that route reflection is not used.

  1. 0 BGP and 2 MP-BGP sessions
  2. 2 BGP and 0 MP-BGP sessions
  3. 2 BGP and 1 MP-BGP sessions
  4. 2 BGP and 2 MP-BGP sessions
  5. 1 BGP and 2 MP-BGP sessions

Answer(s): D



Which of the following about BGP Site of Origin (SoO) is FALSE?

  1. The SoO attribute can be used to uniquely identify the site from which a PE learns routes.
  2. Before a PE redistributes a VPN-IPv4 route, it can assign an SoO attribute to the route.
  3. The SoO attribute can be used to prevent loops from a single site with multiple CE-PE connections.
  4. The SoO attribute can be used as matching criteria when redistributing routes from the CE to the PE.
