According to this picture, we can judge:
- A . R4 does not have any IS-IS neighbors
- B . R4 and ee8c.aOc2.baf3 have established IPv4 and IPv6 IS-IS neighbors
- C . R4 and ee8c.aOe2.baf3 only established IPv6 IS-IS neighbors
- D . R4 and ee8c.aOc2.bat3 only established IPv4 IS-IS neighbors
As shown in the figure, all interfaces of the router enable OSPF. Which of the following statements is correct?
- A . The Type1 LSA generated by R2 in area 0 contains 10.0.2.2/32 routing information
- B . The Type5 LSA generated by R2 in area 0 contains 10.0.2.2/32 routing information
- C . The Type2 LSA generated by R2 in area 0 contains 10.0.2.2/24 routing information
- D . The Type3 LSA generated by R2 in area 0 contains 10.0.2.2/32 routing information
An engineer used two routers to test IPv6 services, and simulated the interconnection between headquarters and branches by running BGP4+.
The logical topology of the network is shown in the figure. Regarding the transmission of IPv6 routes between two devices, which of the following statements is wrong?
- A . When routing, the Next_Hop attribute must be an IPv6 global unicast address
- B . BGP4+ transmits routing information between peers through Update messages
- C . If the Update message carries the MP_REACH_NLRI attribute, it means that the advertised route is reachable
- D . When routing, it will carry AS_Path and other recognized mandatory attributes
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?
- A . 6661
- B . 3
- C . 6662
- D . 8888
Part of the configuration of R1 is as follows. Which statement about OSPF on R1 is correct?
- A . The device type of R1 is Level-2
- B . The device type of R1 cannot be determined
- C . The device type of R1 is Leve1-1
- D . The device type of R1 is Level-1-2
Which of the following regarding the configuration description is wrong?
- A . If the DHCP request message received by the GigabitEthemnet0/0/1 interface does not contain the SutOption information of Option82, the device will generate Option82 and insert it into the message
- B . Enabling the DHCP Snooping configuration can be used to prevent DHCP Server counterfeiters from attacking
- C . Configure GigabitEthernet0/0/1 as a trusted interface
- D . Enabling the DHCP Snooping configuration can be used to prevent ARP spoofing attacks
Assuming that the neighbor relationship between BGP routers has been established successfully, the configuration on R1 is as shown in the figure.
Which router can the route entry 10.10.10.0/24 advertised by R1 be delivered to?
- A . R1
- B . R2
- C . R3
- D . R4
According to the configuration shown in the figure below, you can know that how many interfaces of R4 are advertised into IS-IS?
- A . 1
- B . 3
- C . 2
- D . 0
As shown in the figure:
- A . The LSA in the figure is generated by this router
- B . The destination network described by this LSA is 10.0.23.0/24
- C . The type of the LSA is AS-exterma1-LSA
- D . This device is ABR
