질문 # 166
On the network shown in the figure, single-hop BFD is configured on R1 and R2. A network engineer finds that the BFD session goes down. To locate the fault, the network engineer queries the BFD configurations on R1 and R2. According to the configuration information marked in the figure, it can be determined that the mismatched time parameter settings on R1 and R2 causes the BFD session to go down.
정답：B
설명：
# Configuration Snapshot:
On R1:
bash
CopyEdit
bfd toR2 bind peer-ip 10.0.12.2
discriminator local 1
discriminator remote 2
min-tx-interval 1500
min-rx-interval 1500
On R2:
bash
CopyEdit
bfd toR1 bind peer-ip 10.0.12.1
discriminator local 2
discriminator remote 1
# Observation:
* On R1 , both min-tx-interval and min-rx-interval are configured: 1500ms
* On R2 , no timing parameters are explicitly set (defaults are used)
# BFD Timing Behavior (Huawei):
* BFD is bidirectional and can work even if only one side configures the timers .
* As long as the peer can handle the intervals (i.e. doesn't violate capabilities), the session should still come up .
* This is not a mismatch fault . It ' s valid to set time parameters only on one side.
# Therefore, the time parameter mismatch is NOT the reason the session goes down.
# Final answer: B. FALSE
Root Cause (Likely):
* The real cause might be something else (e.g., interface down, ACL blocking BFD packets, wrong IP, or unidirectional loss).
* But not mismatched timers - they are allowed.
Official Huawei Extract:
" If only one end of the BFD session specifies the detection intervals, the BFD session can still be established. Huawei devices accept remote minimum intervals and negotiate accordingly. "

질문 # 167
As shown in the figure, R1, R2, R3, and R4 are in the same PLs domain, and LDP is used to distribute IPLS labels between devices.
R4 is the Egress LSR of the FEC 4.4.4.0/24. If you want to achieve R1 access 4.4.4.0/24, R4 does not need to query the label table but can know the forwarding priority of the data, then the outgoing label of R3 for the FEC should be:____. (Please fill in the Arabic numerals directly, without symbols)

질문 # 168
On the network shown in the figure, IS-IS IPv6 runs on R2, R6, and R3 , and the IPv6 address of Loopback0 on R6 is 2000::6/128 . OSPFv3 runs on other links. Area 1 is a stub area, and Area 2 is an NSSA . IS-IS routes are imported to OSPFv3 on R2 and R3 . Which of the following statements are false?
정답：A,C
설명：
Comprehensive and Detailed In-Depth Explanation:
To determine which statements are false , we need to understand how OSPFv3 and IS-IS work together , and how Inter-Area-Router LSAs (Type 3 LSAs) are generated in OSPF:
1. Understanding OSPF Inter-Area LSAs (Type 3)
* OSPF generates Type 3 LSAs (Inter-Area-Prefix LSAs) to advertise networks between areas.
* Only Area Border Routers (ABRs) generate Inter-Area LSAs.
* Type 3 LSAs allow routes to be advertised from one OSPF area to another (e.g., from Area 0 to Area 1 or Area 2).
2. Analysis of Each Answer Option:
# A. " R3 generates an Inter-Area-Router-LSA in Area 0. " # TRUE
* R3 is an ABR (connecting IS-IS and OSPF Area 0).
* Since R3 is importing IS-IS routes into OSPFv3 , it must generate Type 3 LSAs to advertise those routes in Area 0 .
* This statement is correct.
# B. " R2 generates an Inter-Area-Router-LSA in Area 0. " # TRUE
* R2 is also an ABR (connecting IS-IS and OSPF Area 0).
* Like R3, R2 imports IS-IS routes into OSPFv3 and advertises them into Area 0 using Type 3 LSAs.
* This statement is correct.
# C. " R1 generates an Inter-Area-Router-LSA in Area 2. " # FALSE
* R1 is not an ABR.
* Only ABRs generate Type 3 LSAs, and R1 is not an ABR between Area 2 and Area 0.
* This statement is false.
# D. " R2 generates an Inter-Area-Router-LSA in Area 1. " # FALSE
* Area 1 is a stub area, and stub areas do not allow Inter-Area-Router LSAs (Type 3 LSAs) for external routes.
* R2 does not generate Inter-Area LSAs in Area 1 because OSPF prevents this in stub areas.
* This statement is false.
질문 # 169
On the OSPF network shown in the figure, the cost values of links are marked. IS-IS Auto FRR is enabled on R1 . The primary path from R1 to 10.0.3.3/32 is R1 # R2 # R3 , and the backup path is R1 # R4 # R2 # R3 .
Is this statement TRUE or FALSE ?
정답：B
설명：
Comprehensive and Detailed In-Depth Explanation:
Step 1: Analyzing the Primary Path
* The given network uses IS-IS Auto FRR , which ensures a backup route in case of failure.
* The shortest path from R1 to 10.0.3.3/32 is calculated based on the OSPF link costs:
* Path 1 (Primary Path): R1 # R2 # R3
* Cost: 10 (R1#R2) + 5 (R2#R3) = 15 #
Step 2: Checking the Backup Path
* The statement claims that the backup path is R1 # R4 # R2 # R3 . Let ' s calculate the cost:
* Path 2 (Backup Path via R4): R1 # R4 # R2 # R3
* Cost: 10 (R1#R4) + 50 (R4#R2) + 5 (R2#R3) = 65 # (Too high)
* The backup path should be an alternative shortest path that is as close as possible to the primary path in cost .
* R1 # R4 # R2 # R3 is not a feasible backup path because the cost (65) is significantly higher than the primary path (15).
Step 3: Correct Backup Path Selection
* If IS-IS Auto FRR is enabled, a feasible backup path should have a cost close to the primary path.
* In this scenario, no viable alternative path meets the Auto FRR requirements efficiently.
* The given backup path is incorrect.
Final answer: # FALSE (Option B)

질문 # 170
On the OSPF network shown in the figure, area 1 is an NSSA, area 2 is a stub area, and R4 imports an external route 10.0.4.4/32. The router ID of each router is 10.0.X.X, where X is the router number. The asbr-summary 10.0.4.0 255.255.255.0 command is configured in the OSPF processes of R1 and R3.
Match the following descriptions of routing tables with the corresponding routers:
정답：
설명：
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Key OSPF Concepts to Consider:
* Area 1 is an NSSA (Not-So-Stubby Area):
* NSSAs allow external routes but advertise them as Type-7 LSAs.
* The ABR (R2) converts these Type-7 LSAs into Type-5 LSAs for the backbone (Area 0).
* Area 2 is a Stub Area:
* Stub areas do not allow external routes (Type-5 LSAs).
* This means that R5 (inside Area 2) will NOT receive external routes like 10.0.4.4/32 or
10.0.4.0/24.
* Effect of asbr-summary 10.0.4.0 255.255.255.0 on R1 and R3:
* This command ensures that R1 and R3 will see a summarized route 10.0.4.0/24 instead of specific /32 routes.
Routing Table Analysis:
* R1 (ABR for NSSA, with ASBR summary configured)
* Connected to Area 1 (NSSA) and Area 0 (Backbone)
* Since asbr-summary 10.0.4.0 255.255.255.0 is configured on R1, it contains both 10.0.4.4/32 (from R4) and the summarized 10.0.4.0/24.
* # Matches Option 4: The routing table contains both 10.0.4.4/32 and 10.0.4.0/24.
* R5 (Inside Area 2 - Stub Area)
* Stub areas do not receive external routes (Type-5 LSAs).
* Since R5 is inside a stub area, it does not contain 10.0.4.4/32 or 10.0.4.0/24.
* # Matches Option 3: The routing table does not contain 10.0.4.4/32 or 10.0.4.0/24.
* R2 (ABR between NSSA and Backbone, but no ASBR summary configured)
* R2 converts Type-7 LSAs from R4 into Type-5 LSAs and advertises them into Area 0.
* Since no ASBR summary is configured on R2, it only sees the specific external route 10.0.4.4
/32 but not the summarized 10.0.4.0/24.
* # Matches Option 1: The routing table contains 10.0.4.4/32 only.
* R3 (Another ABR with ASBR summary configured)
* R3 has asbr-summary 10.0.4.0 255.255.255.0 configured, which means it will summarize the external routes.
* Instead of 10.0.4.4/32, R3 will only have the summarized 10.0.4.0/24 route.
* # Matches Option 2: The routing table contains 10.0.4.0/24 only.
