In an MPLS network, an LSR ID is used to uniquely identify an LSR (Label Switching Router). The LSR ID defaults to the IP address of a physical interface of the device and can be manually configured as the loopback interface address.
- A . True
- B . False
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 is wrong?
- A . Ping any non-existent IP address on R1, such as 10.0.4.4. The data packet will not be sent from R1.
- B . 10.0.1.1 can ping 10.0.3.3
- C . 10.0.1.1 can ping 10.0.2.2
- D . 10.0.2.2 can ping 10.0.3.3
The Route-LSA generated by a router is shown in the figure. Which of the following descriptions are correct? (Multiple choice)
- A . The router belongs to the stub area
- B . Other routers can forward IPv6 traffic through this router
- C . The router is an ABR
- D . The router is the DR of the local link
In the OSPFv3 network shown in the figure, area 1 is a normal area. Which of the following descriptions are wrong? (Multiple choice)
- A . Since R4 and R5 are in the same area, the LSDB of R4 and R5 are the same.
- B . Since R4 and R5 are in the same area, if R4 generates an Intra-Area-Prefix-LSA, the LSA will be sent to R5.
- C . Since area 1 is not continuous, R4 and R5 cannot obtain the route to the IPv6 address of each other’s interface
- D . Since R4 and R5 are in the same area, if R5 imports an external route, R4 does not need to rely on Inter-Area-Router-LSA when calculating the external route.
In the network shown in the figure, adjacent routers use directly connected interfaces to establish EBGP neighbor relationships. The AS number is 6500X , where X is the router number. R1 and R4 both have static routes to 192.168.1.0/24, which are introduced into BGP through import. By default, in the R3 routing table, the AS_Path attribute carried by the route entry to 192.168.1.0/24 is which of the following?
- A . 65006, 65005, 65004, 65001
- B . 65004, 65002, 65005
- C . 65006, 65005, 65004
- D . 65002, 65001
In the network shown in the figure, adjacent routers use directly connected interfaces to establish EBGP neighbor relationships. The Router ID of each device is 10.0.XX, and the AS number is 6500X, where X is the router number. R1 and R4 both have static routes to 192.168.1.0/24, which are introduced into BGP through import.
Which of the following statements are correct by default? (Multiple choice)
- A . The traffic path from R3 to 192.168.1.0/24 is R3-R2-R1
- B . The traffic path from R5 to 192.168.1.0/24 is R5-R4
- C . The traffic path from R2 to 192.168.1.0/24 is R2-R1
- D . The traffic path from R6 to 192.168.1.0/24 is R6-R5-R4
Which of the following reasons will cause Telnet login failure of network devices? (Multiple choice)
- A . Telnet port is disabled
- B . The Telnet service function of the network device is not enabled
- C . Username and password are wrong
- D . The client’s IP address is blocked
In the OSPFv3 network shown in the figure, the interconnected ports of R1, R2, and R3 have OSPFv3 enabled, and the Router ID of each device is 10.0.XX, where X is the device number. Check the detailed information of a certain LSA on R3. From the output information, it can be inferred that the LSA is generated by R2, and it describes the IPv6 prefix address associated with the Network-LSA.
- A . True
- B . False
In the BGP/MPLS IP VPN network, VPN4 routes can be transmitted between PE devices through the BGP-4 protocol.
- A . True
- B . False
In the OSPF network shown in the figure, the network engineer found that the Router ID configuration of R1 and R2 is the same, and both R1 and R2 have introduced the default route (default-route-advertise always). Which of the following descriptions of this scenario is wrong?
- A . R1 and R2 can establish a neighbor relationship
- B . R2 and R4 can establish a neighbor relationship
- C . A routing loop may occur between R3 and R4
- D . R1 and R3 can establish a neighbor relationship
