Q: 1
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: .

Q: 11
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)

Q: 12
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) H12 831 V1 question
