OSPF supports equal-cost load balancing. When the number of equal-cost routes in the network is greater than the number of equal-cost routes configured by the maximum load-balancing command, if the interface priority and interface index are the same, load balancing selects the route with a smaller next-hop IP address.
- A . True
- B . False
The MPLS architecture is divided into a control plane and a forwarding plane, which contains multiple protocols and tables. Which of the following tables is responsible for forwarding packets with MPLS labels?
- A . Forwarding Information Table FIB
- B . Label Information Table LIB
- C . Road and electricity information table RIB
- D . Label Forwarding Information Table LFIB
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. In AS 65000, R1, R3, R4, and R6 all establish IBGP neighbor relationships with R2 and R5, of which R2 and R5 are RRs. R1, R4, R3, and R6 are clients, and IBGP neighbor relationships are all established using the Loopback0 interface. The IP address of the Loopback0 interface of each device is 10.0.XX/32. The Router ID is 10.0.XX, where X is the device number. R1 and R4 introduce the external network 192.168.1.0/24 into BGP through import, and R3 and R6 introduce the external network 192.168.2.0/24 into BGP through import.
Which of the following descriptions are correct by default? (Multiple choice)
- A . For 192.168.2.0/24, R2 prefers the BGP route received from R3
- B . For 192.168.2.0/24, R5 prefers the BGP route received from R3
- C . For 192.168.1.0/24, R6 prefers the BGP route received from R2
- D . For 192.168.1.0/24, R3 prefers the BGP route received from R2
A network engineer uses the capture-packet tool to capture the message received by the interface. The figure shows some output information. It is known that the message is a message of a dynamic routing protocol. Then the protocol is ().
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 routers have a default route in their routing table? (Multiple choice)
- A . R2
- B . R4
- C . R1
- D . R3
In the OSPFv3 network shown in the figure, area 1 is a stub area, area 2 is a common area, and area 3 is an NSSA area. The IPv6 address of the R5 Lopback0 interface is 2000::5/128, which is introduced into OSPFv3 through import. The Router ID of each device is 10.0.X.X, where X is the device number.
Which of the following descriptions are correct? (Multiple choice)
- A . R1 will generate AS-Externa1-LSA
- B . R2 will generate Inter-Area-Router-LSA in area 0
- C . R3 will generate AS-Externa1-LSA
- D . R2 will generate Inter-Area-Router-LSA in Area 2
A network engineer uses the capture-packet tool to capture the message received by the interface. The figure shows some output information. What protocol does this message belong to?
- A . LACP
- B . LLDP
- C . OSPF
- D . BGP
The normal operation environment of the equipment is the prerequisite for ensuring the normal operation of the equipment. When checking the equipment operation environment, which of the following items need to be checked? (Multiple choice)
- A . Power supply
- B . Routing Table
- C . Humidity
- D . Temperature
The address family information field of MP_REACH_NLRI consists of a 2-byte address family identifier AFI and a 1-byte sub-address family identifier SAFI. When public IPv4 routes are transmitted under the BGP-IPv4 unicast address family, SAFI is 1. When public IPv6 routes are transmitted under the BGP- IPv6 unicast address family, SAFI is also 1.
- A . True
- B . False
VLAN aggregation is deployed in a switching network, where Sub-VLAN 2 and Sub-VLAN 3 are added to Super-VLAN 10. If hosts in different Sub-VLANs want to communicate with each other, the command () inter-sub-vlan-proxy enable should be entered in the VANIF 10 interface view corresponding to Super-LAN.
