Question 32

According to this picture, we can judge:

  1. R4 does not have any IS-IS neighbors
  2. R4 and ee8c.aOc2.baf3 have established IPv4 and IPv6 IS-IS neighbors
  3. R4 and ee8c.aOe2.baf3 only established IPv6 IS-IS neighbors
  4. R4 and ee8c.aOc2.bat3 only established IPv4 IS-IS neighbors

Question 33

As shown in the figure, all interfaces of the router enable OSPF. Which of the following statements is correct?

  1. The Type1 LSA generated by R2 in area 0 contains 10.0.2.2/32 routing information
  2. The Type5 LSA generated by R2 in area 0 contains 10.0.2.2/32 routing information
  3. The Type2 LSA generated by R2 in area 0 contains 10.0.2.2/24 routing information
  4. The Type3 LSA generated by R2 in area 0 contains 10.0.2.2/32 routing information

Question 34

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?

  1. When routing, the Next_Hop attribute must be an IPv6 global unicast address
  2. BGP4+ transmits routing information between peers through Update messages
  3. If the Update message carries the MP_REACH_NLRI attribute, it means that the advertised route is reachable
  4. When routing, it will carry AS_Path and other recognized mandatory attributes

Question 35

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?
