  2. All BGP attribute values must be removed before receiving the routes.
  3. The BGP local-preference value that is used by ISP-A is not advertised to R3.
  4. By default, the next-hop value for these routes is not changed by ISP-A before being sent to R3.
Correct answer: AC
Question 6
You have an L2VPN connecting two CEs across a provider network. The CEs and provider network are configured with the default MTU setting. You use the ping command from one CE to the other CE with a size of 1500 bytes.

  1. If a point-to-point interface is in both L1 and L2, separate hello messages are sent for each level.
  2. If a point-to-point interface is in both 11 and L2, one combined hello message is sent for both levels.
  3. If a broadcast interface is in both L1 and L2, separate hello messages are sent for each level.
  4. If a broadcast interface is in both L1 and L2, one combined hello message is sent for both levels.
