The BGP protocol supports the use of the "filter-policy acl-number import" command to subtract the received routing information. The value range of acl-number is 2000~3999.
In the OSPFv3 network shown in the figure, area 1 is a stub area, area 2 is a common area, and area 3 is an NSSA area. The IPv6 address of the R5 Lopback0 interface is 2000::5/128, which is introduced into OSPFv3 through import. The Router ID of each device is 10.0.X.X, where X is the device number.

Which of the following descriptions are correct? (Multiple choice)
In the enterprise network shown in the figure, R3 is connected to the enterprise network management server, and all devices in the network communicate with the network management server through VPN.

During the inspection, it was found that R3 had redundant RT configurations. Which of the following commands can be executed on R3 to delete the redundant RTs without affecting the connectivity of all devices and the network management server? (Multiple choice)
If the users connected to the switch change frequently, you can convert the dynamic MAC address to a sticky MAC address through port security. In this way, when the user changes, the bound old MAC address table entry can be cleared in time through the aging of the table entry.
In the network shown in the figure, R1 and R2 use the direct connection interface to establish a BGP neighbor relationship. There is debug information on R2 as shown in the figure. Please match the following content according to the information.




In the OSPF network shown in the figure, R1 and R2 are connected by four links. OSPF is enabled on the Loopback0 interface of R2. The "maximum load-balancing 3" command is configured in the OSPF process of R1. Which of the following is the outbound interface from R1 to the Loopback0 interface of R2?

In the network shown in the figure, R1 and R2 are configured with single-hop BFD detection. The network engineer found that the BFD session was Down, so he queried the BFD-related configurations of R1 and R2. The configuration information has been marked in the figure.
In addition, the network engineer performed the Ping 10.0.12.2 operation on R1, and the output information is shown in the figure.

Based on this, the possible reason for the BFD session going Down is that the packets with UDP port 4784 are rejected.
Before upgrading or downgrading the system, use the "display ()" command to view the system software, backup system software, configuration files, license files, patch files, and voice files related to the current and next startup of the device.
When a network engineer logs in to a NetEngine AR6120 through the console port, he finds that the password is wrong and cannot log in. If the device can still be logged in through the Telnet account and the user account has the permission to change the console port password, he can log in to the device through Telnet and change the console port password.
In the network shown in the figure, R1, R2, R4, and R5 run IS-IS, and the area number is
49.0001. R3 and R6 run IS-IS, and the area number is 49.0002. Within AS 65000, R1, R3, R4, and R6 all establish IBGP neighbor relationships with R2 and R5, where R2 and R5 are RRs and R1, R4, R3, and R6 are clients. R2 and R5 also establish an IBGP neighbor relationship and configure the same Cluster ID. IBGP neighbor relationships are all established using the Loopback0 interface. The IP address of the Loopback0 interface of each device is 10.0.X.X/32, and the Router ID is 10.0.X.X, where X is the device number. R1 and R4 introduce the external network 192.168.1.0/24 into BGP through import. For 192.168.1.0/24, match based on the number of valid routes in the BGP routing table.



In the IS-IS network shown in the figure, R1 introduces the default route through the "default- route-advertise always level-1" command. Which device is the next hop corresponding to the default route in R3's routing table?
