NEW QUESTION # 34
A network environment looks like:
HostA----GE0/0--MSR-1--S1/0-----Frame Relay----S1/0--MSR-2--GE0/0----HostB
Among them, two routers MSR-1 and MSR-2 connect to the frame relay network through S1/0 respectively. Configure IP addresses 3.3.3.1/24 and DLCI 31 on the S1/0 interface of MSR-1, and configure IP addresses 3.3.3.2/24 and DLCI 82 on the S1/0 interface of MSR-2. The physical connection is completely normal, and the other default configurations are the same.
So which of the following statements are wrong? (multiple choice)
- A. On a frame relay network, the corresponding relationship between DLCI 31 connected to MSR-1 and DLCI 82 connected to MSR-2 must be correctly configured, so that the S1/0 interfaces of the two routers can communicate with each other.
- B. In the frame relay network exchange process, the source DLCI is always 31, and the destination DLCI will change. Until the last hop, the destination DLCI becomes 82.
- C. On a frame relay network, DLCI 31 can identify MSR-1, and DLCI 82 can identify MSR-2.
- D. After configuring the command ip address negotiate on the S1/0 interface of MSR-1, it can dynamically obtain the address from MSR-2.
