Which of the following statements is NOT a valid reason to use MP-BGP as a routing protocol to transport VPRN routes?

  1. The number of VPRN routes can become very large. MP-BGP can support a very large number of routes.
  2. MP-BGP can carry routing information for a number of different address families.
  3. MP-BGP is designed to exchange information between routers that are not directly connected.
    This feature keeps VPRN routing information out of P-routers.
  4. MP-BGP can carry additional information attached to a route as an optional BGP attribute.
  5. All of the above statements are valid reasons for using MP-BGP as a VPRN routing protocol.

Answer(s): E



Which of the following statements best describes a route target?

  1. A route target is a BGP extended community used to identify the VRF table for a prefix at the receiving PE
  2. A route target is a mechanism from which VPRN controls the distribution of VPN routing information.
  3. Route target attributes are earned in a MP-BGP as attributes of the route.
  4. A route target is used by the PE router to identify the VRF that a VPN-lPv4 prefix is associated with.
  5. All of the above statements describe a route target
  6. None of the above statements describe a route target

If CE1 and PE1 use BGP to exchange routing information and CE2 and PE2 use static routing to forward traffic to and from the VPRN, which of the following statements is considered TRUE?

  1. An export policy is required on PE1 to advertise routes to CE1.
  2. An export policy is not required on PE2 to advertise routes to CE2.
  3. An export policy is not required to advertise routes between PE routers
  4. All of the above statements are true
  5. All of the above statements are false

Answer(s): D



Which of the following statements is TRUE concerning a VPRN data plane flow?

  1. A data packet will receive a service label at the CE and a transport label at the ingress PE.
  2. A data packet intended for a remote CE will have its service label swapped at each P router along the path towards the egress PE.
  3. At the egress PE, the transport label will be popped and the data packet forwarded with the service label.
  4. The service label is popped by the remote CE. The unlabeled packet is forwarded based on the longest match lookup algorithm in the VRF.
  5. All of the above statements are false.
  6. All of the above statements are true.
