On the network shown in the figure, IS-IS runs on R1, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. In AS 65000, R1, R3, R4, and R6 each establish iBGP peer relationships with R2 and R5. R2 and R5 are RRs (Route Reflectors), and R1, R4, R3, and R6 are clients. The iBGP peer relationships are established using Loopback0 on each router, and the router ID is 10.0.0.X/32, where X is the number of the router. R1 and R4 import the external route 192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import- route command. Which of the following statements are true?

• A. The routing table of R4 contains two equal-cost default routes.
• B. The route 192.168.1.0/24 in the routing table of R3 has two next hops.
• C. For 192.168.1.0/24, R3 preferentially selects the BGP route received from R2, and R6 preferentially selects the BGP route received from R5.
• D. The routing table of R1 does not contain the route 192.168.2.0/24.

In the figure, a network administrator configures a static LSP to implement MPLS data forwarding . The lower part of the topology shows the packet header information obtained from a device.
Which of the following statements are true ?

Options:

• A. If the device is R3, R3 forwards the packet from PC1 to PC2 over an IP route.
• B. Packets from PC2 to PC1 are forwarded based on the IP packet header in the MPLS domain.
• C. PC1 pings PC2.
• D. Packets from PC1 to PC2 are forwarded based on MPLS labels in the MPLS domain.

OSPFv3 runs on R1 and R2 , and the IPv6 addresses configured for the interfaces are marked in the figure .
The router IDs of R1 and R2 are 10.0.1.1 and 10.0.2.2, respectively .

Which of the following statements is true ?

• A. The Intra-Area-Prefix-LSA generated by R1 describes three prefixes.
• B. The Intra-Area-Prefix-LSA generated by R1 describes four prefixes.
• C. The Intra-Area-Prefix-LSA generated by R2 describes three prefixes.
• D. The Intra-Area-Prefix-LSA generated by R2 describes four prefixes.

An OSPFv3 NSSA LSA is generated by an ASBR , describes routes to a destination outside the AS , and is advertised in an NSSA .
Options:

• A. TRUE
• B. FALSE

In the figure, packets are forwarded based on MPLS on the network .
When PE2 receives a packet from P2 , what is the label value carried in the packet?

Options:

• A. The label value is 3.
• B. The label value is 1033.
• C. There is no label.
• D. The label values are 3 and 1033.
