In the diagram, the BGP import policy "north-and-south" is applied to router R5. Router R1 advertises the prefix 140.100.1.0/24 with a community set to "65200:1". Which of the following statements about how router R5 processes the received route update for prefix 140.100.1.0/24 is TRUE?

  1. The prefix is rejected.
  2. The prefix's local preference is set to 20.
  3. The prefix's community value is removed.
  4. The prefix's community value is modified to 65200:2.

  2. The second label is a BGP label pushed by router RBR1.
  3. The service label is a label pushed by router PE1.
  4. The outer label will be popped by router Core2.

  2. Either RSVP, LDP, or segment routing tunnels need to be established between regions.
  3. Either RSVP, LDP, or segment routing tunnels need to be established within each region.
  4. Each PE router needs to advertise an IP address as a labeled BGP route to identify the tunnel endpoint.

Answer(s): B
