As shown in the figure, R1, R2, R3, and R4 are in the same PLs domain, and LDP is used to distribute IPLS labels between devices. R4 is the Egress LSR of the FEC 4.4.4.0/24. If you want to achieve R1 access 4.4.4.0/24, R4 does not need to query the label table but can know the forwarding priority of the data, then the outgoing label of R3 for the FEC should be: . (Please fill in the Arabic numerals directly, without symbols)

The configuration shown is performed on R2 to filter all incoming routes. Suppose there is a BGP route with the AS_Path attribute of [100200300400] on R1 that needs to be sent to R2. Please help the network administrator to adjust the AS order in the AS_Path attribute of the route on R1 to ensure that the route entry will not be filtered by the routing policy of R2 , , , . 100 This space corresponds to the [A] space in the routing policy 200 This space corresponds to the [B] space in the routing policy 300 This space corresponds to the [C] space in the routing policy 400 This space corresponds to the [D] space in the routing policy

In OSPFv3, an LSA whose propagation range is one area has kind. (Fill in Arabic numerals only)

by executing The command can completely isolate the second and third layer users of different ports on the same LAN and cannot communicate. (Please use English and lowercase letters to complete the command, and the command cannot be abbreviated)

As shown in the figure, OSPF is enabled on all interfaces of the router, and the ip address identified in the figure is the device's IP address. Loopback0 presses the IP address of the port, RI, R2, R3EJLoopbacD is advertised in the area 1, R4 LoopbacfkD advertises in area D and which of the following functional addresses can be pinged between the LoopbackD announcements of R5 and R5 in area 2?

Please match 0SPFv3LSA with its transmission range.

During the daily troubleshooting process, engineers may need to view some alarm information of the device. Run the terminal command to enable the terminal to display the debugging/log/alarm information sent by the information center.
