All routers in a network run IS-IS, and all are in Area 49.0001, where the L SDB of R1 is shown in the figure According to this, it is judged that the DIS of Level-2 is.

Please match 0SPFv3LSA with its transmission range.

OSPF is deployed in a campus to achieve network interworking, and OSPF is also enabled on the GEO/0/2 interface of R3. Area1 is deployed as an NSSA area, and the device addresses are shown in the figure. An engineer configures a static route on R3 to access the loopback interface address of R4, and imports the static route in the 0SPF process. At this point, in the Type5 LSA received by R1, the forwarding address (FA) is . (Note: Please fill in the IP address without mask)

IGP converges faster than BGP, which may cause network traffic loss. By enabling the OSPF and BGP linkage feature of the device, the device can keep the OSPF and BGP linkage during the set linkage time. The router makes the link metric value in the LSA advertised to be the maximum value, so as to inform other OSPF devices not to use this router to forward data, so as to avoid traffic loss. (Note: If English letters are involved, all uppercase)

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)

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

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.

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)

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?
