In the OSPF network shown in the figure, area 1 is an NSSA area, area 2 is a common area, and R4 imports the external route 10.0.4.4/32. The Router ID of each device is 10.0.XX, where X is the device number.
The "asbr-summary 10.0.4.0 255.255.255.0" command is configured in the OSPF processes of R1 and R3. Which of the following routers have a route entry for 10.0.4.0/24 in their routing tables? (Multiple choice)
- A . R1
- B . R5
- C . R3
- D . R2
In the network shown in the figure, R1, R2, R4, and R5 run IS-IS in area 49.0001, R3 and R6 run IS-IS in area 49.0002, and "import-route isis level-2 into level-1" is configured on R2 and R5. Within AS 65000, R1, R3, R4, and R6 all establish IBGP neighbor relationships with R2 and R5, of which R2 and R5 are RRs, and R1, R4, R3, and R6 are clients. R2 and R5 also establish an IBGP neighbor relationship and configure the same Cluster ID. IBGP neighbor relationships are all established using the Loopback0 interface. The IP address of the Loopback0 interface of each device is 10.0.X.X/32, and the Router ID is 10.0.X.X, where X is the device number. R1 and R4 import the external network 192.168.1.0/24 into BGP, and R3 and R6 import the external network 192.168.2.0/24 into BGP. In the BGP process of all routers, configure "maximum load-balancing ibgp 8".
Which of the following descriptions are correct by default? (Multiple choice)
- A . There are two equal-cost routes to 192.168.2.0/24 in R5’s routing table.
- B . There are two equal-cost routes to 192.168.1.0/24 in R2’s routing table
- C . R1’s routing table has an equal-cost route to 192.168.2.0/24, and the next-hop IP is the same.
- D . R3’s routing table has an equal-cost route to 192.168.1.0/24, and the next-hop IP is different.
In the network shown in the figure, OSPF protocol runs between R1, R2, and R3. IBGP neighbor relationship is established between R1 and R3 using loopback interface, and BFD function is enabled in BGP process. BFD parameters are "bfd min-tx-interval 1000 min-rx-interval 1000 detect-maltiplier6". If OSPF is disabled on GE0/0/1 interface of R2 through "undo network xxxx yyyy" command, and BGP neighbor relationship is checked on R1, by default, the longest time for R1 BGP neighbor relationship to change from up state to down state is which of the following?
- A . 180s
- B . 6s
- C . 40s
- D . 60s
When dealing with a fault in the existing network, a network engineer drew a topology diagram as shown in the figure. All routers run SPF. Which of the following descriptions about the access path between PC1 and PC2 is correct?
- A . The path from PC1 to PC2 is: PC1-R1-R3-R2-PC2; the path from PC2 to PC1 is: PC2-R2-R3-R1-PC1
- B . The path from PC1 to PC2 is: PC1-R1-R3-R2-PC2; the path from PC2 to PC1 is: PC2-R2-R1-PC1
- C . The path from PC1 to PC2 is: PC1-R1-R2-PC2: The path from PC2 to PC1 is: PC2-R2-R3-R1-PC1
- D . The path from PC1 to PC2 is: PC1-R1-R2-PC2, and the path from PC2 to PC1 is: PC2-R2-R1-PC1
