Question 16
IEIF has extended the functions of OSPF by taking advantage of the strong scalability of OSPF. To enable it to support IPv6 networks, the expanded protocol is called OSPFv3, and OSPFv3 is compatible with OSPFv2.
Question 17
On the OSPF network shown in the figure, area 1 is an NSSA, area 2 is a stub area, and R4 imports an external route 10.0.4.4/32. The router ID of each router is 10.0.X.X, where X is the router number. The asbr-summary 10.0.4.0 255.255.255.0 command is configured in the OSPF processes of R1 and R3.
Match the following descriptions of routing tables with the corresponding routers:

Match the following descriptions of routing tables with the corresponding routers:

Question 18
As shown in the figure, the MP_BGP neighbor relationship is established between PE1 and PE2 through the LoopbackO interface. After the configuration is complete, it is found that CE1 and CE2 cannot learn routes from each other. Which of the following options will cause this problem.


Question 19
In the process of viewing the debug output through the SSH terminal, a lot of information pops up. Which of the following operations can Make the Moni tor terminal no longer pop up debug messages?
Question 20
The configuration shown is performed on R2 to filter all incoming routes. Suppose there is a BGP route with the AS_Path attribute of [100200300400] on R1 that needs to be sent to R2. Please help the network administrator to adjust the AS order in the AS_Path attribute of the route on R1 to ensure that the route entry will not be filtered by the routing policy of R2____, ____, ____, ____.
