NEW QUESTION 235
Two MSR routers are connected via Ethernet and serial interfaces respectively, as shown in the figure. The PPP link layer protocol is running on the serial link, and OSPF is running on the two routers, and both belong to Area 0. At the same time, the three network segments on each router (GE interface network segment) are published in Area 0 through the network command. , Serial interface network segment, LAN network segment);
At present, the OSPF neighbors on both ends are stable, so ______. (Multiple choice)
- A. As long as the OSPF Cost values of the GE interface and the serial interface of the two routers are correctly modified, then two equal-value routes to each other's LAN will be formed on RTA and RTB.
- B. On the GE link, RTA and RTB will still conduct DR and BDR elections
- C. If the OSPF Cost value is not modified, then the LAN segment from RTA to RTB will be the GE link
- D. All the above statements are correct
Answer: A,B,C,D
