QUESTION 160
In the IS-IS network shown in the figure, after the routes of each router are stable, the IS-IS Level-1 routes in the IS-IS LSDB of the RTE have ______.

QUESTION 161
As shown in the figure, RTA and RTB act as border routers between the BGP routing domain and the OSPF routing domain.
In order to realize the routing intercommunication between the BGP routing domain and the OSPF routing domain, the following route distribution strategy is not feasible: _______

QUESTION 162
When the area authentication and domain authentication are configured in IS-IS, the IS-IS message types to be verified include _________.

QUESTION 163
B As shown in the figure, RTA, RTB, and RTC run OSPF, and the process number is 100; OSPF process 200 runs between RTA, RTB, and RTD. The cost of all interconnected links is set to 10. Set the external route priority of OSPF 100 on RTA and RTB to 190, and import an external route 172.16.1.0/24 into OSPF 100 on RTC. Both RTA and RTB are configured to import OSPF100 routes into OSPF200.
According to the above scenario analysis, the following description about RTD learning external routing 172.16.1.0/24 is correct.

QUESTION 164
The two routers cannot establish OSPF neighbors. The following possible reasons are ________.

QUESTION 165
In IPv6 stateless address autoconfiguration, which of the following ways can PC get router RA message?

QUESTION 167
In OSPF protocol, ASBR cannot aggregate LSA types:

QUESTION 168
An MSR router has four interfaces whose IP addresses are Loopback0:1.1.1.1/32, Loopback1:2.2.2.2/32, GE0/0:172.16.1.1/30, and GE0/1:192.168.1.1/30. Running OSPF protocol and enabling OSPF on only two interfaces, the Router ID selected by this router is _______.

QUESTION 169
In the IS-IS network as shown in the figure, after the routes of each router are stable, there are ______ IS-IS Level-2 routes learned by RTA through neighbors.

QUESTION 170
The administrator wants to configure the OSPF routing priority value on the MSR router as 60. Which of the following commands is correct?

QUESTION 171
Which of the following commands is used to reset PBR statistics?

QUESTION 172
L is a network design engineer. In a certain network project, in order to reduce the complexity, the small L design network adopts a two-layer architecture, and the access layer functions are incorporated into the convergence layer. In the design, the small L takes into account that the core layer needs to have a fast convergence function, and the convergence layer performs route aggregation to reduce the number of routes. Among the following routing protocols, which one should be used by Little L as the core layer routing protocol? (Choose one or more)

QUESTION 173
Regarding the default metric values ​​for route import by different routing protocols, which of the following descriptions is __________
