As shown in the figure, an OSPF multi-process is configured on the RT1 router, wherein process 100 of RT1 establishes an OSPF neighbor through the backbone area with RT2, and process 200 establishes an OSPF neighbor through the backbone area with RT3.
Please select the wrong options:
- A. The router RT1 public network routing table has routes to RT2 and RT3.
- B. The OSPF process on router RT2 can use process 100 and RT1 to establish neighbors.
- C. The router RT3 public network routing table has OSPF routes to RT1 and RT2 routers.
- D. Because both RT1-RT2 and RT1-RT3 establish neighbors through the backbone area, the RT2 OSPF process has the LSA generated by the RT1 OSPF process.
