QUESTION 37
Compared with the OSPFv2 message header, what fields are added in the OSPFv3 message header?

QUESTION 38
As shown in the figure, all interfaces of the router enable OSPF. The IP address identified in the figure is the IP address of the oopback0 interface of the device. Loopback0 of R1 and R2 is advertised in area 1, Loopback0 of R4 is advertised in area 0, and Loopback0 of R3 and R5E are advertised in area 2, which of the following IP addresses can ping each other? (Multiple choice)

QUESTION 39
As shown in the figure, OSPF is deployed in a campus, and Area 1 is deployed as an NSSA area. By default, R2 will automatically generate a Type 7 LSA default route and flood it in the NSSA area.

QUESTION 40
As shown in the figure, the entire network of a certain company uses OSPF to get through the network. However, RouterS and RouterE cannot establish an OSPF neighbor relationship. When detecting OSPF failures, network administrators can execute the display ospf 100 () interface GEO/0/1 command on RouterS to obtain error-related information. Users can perform OSPF failure diagnosis based on this information. (Please use English lowercase letters to complete the command, and the command cannot be abbreviated)

QUESTION 43
As shown in the figure, the operator’s BGP/MPLS IP VPN backbone network builds SP through DP. If you want to implement user X If the two sites communicate through the BGP/MPLS IPVPN network, PE1 and PE2 must use a 32-bit masked loopback interface address to establish an MP-IBGP peer relationship.

QUESTION 44
As shown in the figure, Site1 and Site2 need to achieve mutual access through the operator’s BGP/MPLS IPVPN. It is known that the public network tunnel between PE1 and PE2 has been established (the label information is shown in the figure), and PF1 has advertised the 192.168.1.0/24 network segment route in Site1 to PE2 through the MP.JIBGP neighbor relationship, and the route learning is normal.

When capturing the data that Site2 visits the 192.168.1.0/24 of Site1 between P and PE1, what should be the outermost label?

QUESTION 45
The network administrator A wants to use ACL to match only the four routing entries 1, 3.5, and 7 in the figure. How many ACL rules does the network administrator A need to configure at least?
