質問 246
The WAN interface S0/0 of the customer's two routers MSR-1 and MSR-2 uses the PPP protocol, and the routers learn the routes from each other by configuring RIP. The following configuration is available on MSR-1: rip 1 network 0.0.0.0 import -route static # ip route-static 0.0.0.0 0.0.0.0 Serial0/0 Then the wrong explanation about this configuration is ______.
- A. By configuring MSR-1 as above, the default route can be dynamically advertised to the peer through RIP
- B. RIP 1 in the configuration means that the configured RIP version is V1
- C. RIP imports the statically configured default route and advertises it to MSR-2
- D. Through the above configuration, MSR-1 will not dynamically advertise the default route to the peer through RIP
正解: C,D
質問 247
Router MSR-1 is interconnected with MSR-2 and MSR-3 respectively. Among them, there is a RIP route learned from MSR-2 to the destination network segment 120.10.12.0/24 in the routing table of MSR-1. It is 3; at this time, MSR-1 also receives a RIP route from MSR-3 that is still going to the destination network segment 120.10.12.0/24, and its Cost is 15, then ______.
- A. The routing table of MSR-1 will be updated, because RIP routing with a Cost of 15 means that the network may have loops
- B. The routing table of MSR-1 is not updated, and the network segment route learned from MSR-2 is still retained
- C. The routing table of MSR-1 will be updated to the route learned from MSR-3 to the cost of 15.
- D. The routing table of MSR-1 will not be updated, because RIP routing with a Cost of 15 means unreliable routing, and RIP will not write it into its routing table
正解: B
