NEW QUESTION # 29
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)
Answer: A,B,C,D
NEW QUESTION # 30
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 true?
Answer: A,C,D
Explanation:
# Explanation:
# Network Summary:
* IS-IS (IPv6) runs on: R2 # R3 # R6
* R6 owns Loopback0 = 2000::6/128
* OSPFv3 runs on: R1, R2, R3, R4, R5
* Area 1 = Stub (R4), Area 2 = NSSA (R5)
* Redistribution: IS-IS # OSPFv3 happens on R2 and R3
# Option A: R5 contains 2000::6/128
# True
* Area 2 is NSSA, and by default:
* External routes (like IS-IS) imported via import-route isis on R3 become Type-7 LSAs
* Then translated to Type-5 LSAs by R3 (ABR) for other areas.
* R5 will receive the translated route.
# Option B: R1 contains 2000::6/128
# True
* R2 and R3 redistribute the IS-IS IPv6 route into OSPFv3.
* R1 is in Area 0, directly connected to both R2 and R3.
* It receives the route as a normal OSPFv3 inter-area (Type-3) or external (Type-5) route.
# Option C: R6 contains ::/0 (default route)
# False
* R6 runs IS-IS Level-1 only.
* IS-IS Level-1 routers do not automatically get a default route.
* To get a default route in Level-1, the ABR must explicitly advertise it using:
pgsql
CopyEdit
isis default-route advertise always level-1
* No such configuration is mentioned # R6 does not receive ::/0 by default.
# Option D: R4 contains 2000::6/128
# True
* R4 is in Area 1 (Stub).
* Stub areas block Type-5 LSAs but allow Type-3 (inter-area) LSAs.
* Since IS-IS # OSPF redistribution occurs into backbone (Area 0), and R4 connects to it via R2 (ABR), R4 will receive the route via a Type-3 LSA.
# Final Answer: A, B, D
Official Huawei Extract:
" In OSPFv3, NSSA areas allow Type-7 LSAs, which are converted to Type-5 LSAs by the ABR. Stub areas block external LSAs but allow inter-area (Type-3) LSAs. IS-IS Level-1 routers require explicit default-route injection to receive ::/0. "

NEW QUESTION # 31
When dealing with a fault in the existing network, a network engineer drew a topology diagram as shown in the figure. All routers run OSPF. Which of the following descriptions about the access path between PC1 and PC2 is correct?
Answer: B
NEW QUESTION # 32
On the network shown in the figure, EBGP peer relationships are established between neighboring routers through directly connected interfaces .
* The router ID of each router is 10.0.X.X , and the AS number is 6500X , where X is the number of the router .
* Both R1 and R4 have static routes to 192.168.1.0/24 , which are imported to BGP through the import-route command.
* R1 adds a community attribute (1:1) to the route before advertising it to its peers .
* All routers are configured to propagate community attributes .
* R3 is configured with a routing policy that rejects routes with the community attribute 1:1 .
In this case, which of the following is the path for traffic from R3 to 192.168.1.0/24 ?
Answer: A
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Understanding the BGP Network Topology in the Question:
* BGP Peering & Route Distribution
* Each router forms EBGP peer relationships with directly connected neighbors.
* R1 and R4 import the static route 192.168.1.0/24 into BGP and advertise it to their peers.
* Community attributes are attached to routes to influence routing policies.
* Effect of Community Attribute 1:1
* R1 marks 192.168.1.0/24 with community 1:1 before advertising it.
* R3 has a policy that rejects any routes with community attribute 1:1.
* Since R1's advertisement contains 1:1, R3 will not accept 192.168.1.0/24 from R2.
Route Selection and Traffic Flow Analysis:
* R1 advertises 192.168.1.0/24 with community 1:1 to R2.
* R3 rejects this route from R2 because of the configured routing policy.
* R4 also advertises 192.168.1.0/24 to its EBGP neighbors without community 1:1.
* R5 learns the route from R4 and advertises it to R3.
* Since R5's advertisement does not include community 1:1, R3 accepts the route from R5.
* Thus, the best available path for R3 to reach 192.168.1.0/24 is R3 # R5 # R1.
# Correct Path: R3 # R5 # R1
Checking Each Option:
# Option A: R3 # R2 # R4 (Incorrect)
* R3 does not learn the route from R2 because it rejects community 1:1 .
* Since R1 added 1:1, and R2 propagated the same community, R3 will not accept this path .
# Option B: R3 does not have a route to 192.168.1.0/24 (Incorrect)
* R3 does have a route, but it learns it from R5 instead of R2 .
# Option C: R3 # R2 # R1 (Incorrect)
* R1 marked the route with 1:1, and R2 advertised it with the same community .
* Since R3 rejects 1:1 routes, it will not use this path .
# Option D: R3 # R5 # R1 (Correct)
* R5 learns the route from R4, which does not have community 1:1, and advertises it to R3 .
* R3 accepts this route and forwards traffic to R5, which sends it to R1 .
Final Conclusion:
# D. The correct path for traffic from R3 to 192.168.1.0/24 is R3 # R5 # R1.
Thus, the correct answer is: D .
