NEW QUESTION # 151
An enterprise purchased private lines from two operators. In order to optimize the lines, the enterprise used BGP to learn routing entries from the two operators. However, the enterprise found that the traffic of the egress route increased greatly after this configuration. After the network engineering investigation, it was found that the traffic of the two operators was passed to each other through the enterprise egress router.
Therefore, the enterprise intends to use the routing strategy so that the traffic of the packets of different carriers is no longer passed to each other. Is the configuration in the following figure correct?
- A. FALSE
- B. TRUE
Answer: B

- A. OSPFV3 uses the authentication field in the packet header to complete packet authentication
- B. OSPFv3 uses IPv6 multicast address FF02
- C. OSPFv3 uses the link-local address as the source address of the outgoing packet. The packet can be forwarded outside the range of the originating link
