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?
- A . GE0/0/2.20
- B . GE0/0/1
- C . GE0/0/0
- D . GE0/0/2.10
R4’s Router ID is 10.0.4.4. In R4’s LSDB, the LSA shown in the figure is seen. The network engineer makes the following inferences based on the LSA. Which of them are correct? (Multiple choice)
- A . R4 is the DR on a link
- B . At least one link of R4 does not have an OSPFv3 neighbor relationship established
- C . These three LSAs are located in area 1
- D . Area 1 is a stub area
The MPLS label is a 20-bit local identifier. When the administrator configures a static LSP, the incoming label and outgoing label can be manually specified. The value range is 0~1048575.
- A . True
- B . False
In a BGP/MPLS IP VPN network, PE devices will update VPN routes through Update messages. Which of the following information will be included in the Update message? (Multiple choice)
- A . VPNv4 routing prefix
- B . Public network label value
- C . Next hop address
- D . Export RT value
In the IS-IS network shown in the figure, R1 introduces the default route through the "default-route-advertise always level-1" command. Which of the following descriptions are correct? (Multiple choice)
- A . 10.0.1.1 can ping 10.0.2.2
- B . 10.0.1.1 can ping 10.0.3.3
- C . 10.0.2.2 can ping 10.0.3.3
- D . 10.0.12.2 can ping 10.0.3.3
In the network shown in the figure, IS-IS IPv6 runs between R2, R6, and R3, and the IPv6 address of R6 Looback0 interface is 2000::6/128.
Other links all run OSPFv3. Area 1 is a stub area and Area 2 is an NSSA area.
IS-IS routes are imported into OSPFv3 on R2 and R3. Which of the following methods can enable R4 to ping 2000::6? (Multiple choice)
- A . Configure "ipv6 default-route-advertise always level-1" in the IS-IS process of R3.
- B . Configure "attached-bit advertise always" in the IS-IS process of R2.
- C . Configure "ipv6 default-route-advertise always level-1" in the IS-IS process of R2.
- D . Configure "attached-bit advertise always" in the IS-IS process of R3
Use the "display current-configuration |include 10.0.2.*" command on the router to see all the information including "10.0.2" in the current configuration.
- A . True
- B . False
In the IS-IS IPv6 network shown in the figure, all routers have multi-topology enabled. Configure "ipv6 default-route-advertise always level-1" in the R4 IS-IS process.
By default, which of the following routers has no default route in its routing table?
- A . R3
- B . R1
- C . R5
- D . R2
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. IBGP neighbor relationships are all established using the Loopback0 interface. R2 and R5 also establish an IBG neighbor relationship. The IP address of the Loopback0 interface of each device is 10.0.X.X/32, and the Router ID is 10.0.XX, where X is the device number. R1 and R4 introduce the external network 192.168.0/24 into BGP through import.
For 192.168.1.0/24, match the number of valid routes in the display bgp routing-table output.
An MPLS label is a 20-bit local identifier. Its label space is divided into special labels, static shared label space, and dynamic signaling protocol label space. Which of the following are special labels? (Multiple choice)
- A . 14
- B . 1025
- C . 2
- D . 1022
