Q15. As shown in the figure, 0SPF is enabled on all interfaces of the router. The cost value of the link is marked in the figure, R2’s LoogbackO is advertised by mouth in area 0, then in In area 1, both R2 and R3 transmit the routing information of 10.0.2.2/32 in the form of Typae3 LSA.

Q16. 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?

Q20. When B, CPIMPLS TP VPN is deployeD. the OSPF VPN Route Tag (VPN Route Tag) is not transmitted in the extended community attribute of MP-BGP, but the local concept is only meaningful on PE routers that receive MP-BGP routes and generate OSPF LSAs.

Q21. A certain park deployed both IPv4 and IPv6 networks for service testing, and IS-IS was run to achieve network interconnection. IS-IS routing protocol has good scalability and is widely used in existing networks.
Regarding IS-IS scalability, which of the following statements are correct? (Multiple choice)

Q22. Basic QinQ can select the outer tag encapsulation method according to the type of business.

Q23. A company purchased private lines from two operators. In order to optimize the lines, the company used the 6GP protocol to learn from two Route entries that operate off. However, after the enterprise found that this configuration, the traffic of the port route increased greatly, and the network engineering arrangement After investigation, it was found that the traffic of the two operators was passed to each other through the enterprise egress router. Therefore, the enterprise intends to use the routing strategy so that the traffic of the packets of different carriers is no longer passed to each other. Is the configuration in the following figure correct?

Q24. In BGP/MPLS IP VPN, the 0SPF multi-instance process uses the DN bit to prevent Type5 LSA loops.

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?
